How to use 2nd Ethernet port
Hi all,
I have a QNAP TS-251 plug to my network using 1st ethernet port.
Is it possible to connect a computer to the 2nd ethernet port of the NAS to access to the NAS and to internet ? I tried to connect my labtop. I can connect to the NAs but not to internet.
thanks for your help,
Romuald

Re: How to use 2nd Ethernet port
to access the NAS and internet from several attached computers, get a router with an integrated switch.
The second port can be used for port trunking,accessing the NAS from different subnets, etc.
The router solution would also enable you to forward (certain ports of) the NAS to the web.

Re: How to use 2nd Ethernet port
Since the OP already have an internet connection, and therefore likely a router, I think a better recommendation would be a gigabit switch. If romu@asnieres feel up to learning the management, it could even be a managed switch to allow the use of the more advanced port trunking protocols (Balance-rr, Balance XOR or IEEE 802.3ad). With an unmanaged switch, as in a router-integrated one, the only possible port trunking options are Balance-tlb and Balance-alb.dolbyman wrote:to access the NAS and internet from several attached computers, get a router with an integrated switch.

1. It wasn't asked for.
2. It's likely already possible with the current equipment.
3. Ports shouldn't ever be forwarded because it's possible, but only if it's absolutely necessary.
4. Each port forwarded adds a security risk and every day NASes are hacked because of home users opening up ports without understanding the consequences...
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!
A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.
All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

No - the second Interface can be configured as a host interface - there is no bridging of the two interfaces supported. Beyond, it's strongly suggested to configure a second, independent network segment to a dedicated, different TCP/IP subnetwork than the first segment - just in case.romu@asnieres wrote:and to internet ?

Re: How to use 2nd Ethernet port
If you want to get fancy, or if you have multiple NAS devices, you can operate a second network to connect some of your equipment together on a second network, so you can get Server-to-Server traffic onto it's own dedicated network, so that Server to Server traffic doesn't saturate your main LAN+Internet subnet:romu@asnieres wrote:Hi all,

Re: How to use 2nd Ethernet port
Which answer? You have several in this thread, and I would expect we all provided different pieces of the puzzle for you. (I'd like to think my answer is the "prettiest" , but all the answers in this thread are helpful).romu@asnieres wrote:Many thanks for your answer. Now I relaly understand why I have 2 ethernet ports

Re: How to use 2nd Ethernet port
AS you said all answers are helpful. I don't really need to choose between all answers since I just have simple needs so 1 ethernet port is enough. I was just curious to understand why it has 2 ports I Can say I learn new things today lol

Re: How to use 2nd Ethernet port
Yes, depending on your usage, using a single NIC is far easier to configure and use, and should be more than good enough for 95% of Home NAS users. If you are ever in a "Roommate" living situation, you might find it preferable to connect your NAS to separate networks, so your network can be isolated from your Roommate's network, but your NAS can be connected to both networks, so your Roommate can access your NAS media content, without giving him/her access to your other devices on "your" network.romu@asnieres wrote:AS you said all answers are helpful.

I'm way past Roommates here, but at one point I had a friend living in the other side of my Duplex housing unit. We simply poked an Ethernet cable through the wall, so he could access my NAS on his network. He doesn't live next door anymore, but he liked my NAS so much, he bought his own QNAP before he moved on to another domicile.
If you ever "outgrow" your existing NAS, and decide to get second one, you might find it preferable to connect the NAS devices into a second dedicated network, as depicted in the graphic I previously provided. Getting NAS-to-NAS traffic off your main network can greatly improve your network performance on your main network.

Re: How to use 2nd Ethernet port
I won't share my NAS with my neighbor but I'll probably need to had a NAS to my network one day. I have mine since 2 weeks and it's half full. So your schema is very interesting to optimize traffic network.
thanks again for all these details

Yes, in the original post, the poster (he/she) asked if the second port could be used for external access from the internet or at least that's how I understood it

Re: How to use 2nd Ethernet port
Sorry for the noob question,but i've a similar problem.I use with success the 1st port with static ip.The nas is correctly linked to the switch and can download files ecc ecc.
I want now to connect to the nas using also the 2nd port...if i set static ip i can't access to the nas,also if i enable dhcp i have ips like 169.254.xxx.xxx and of course i can't access.
I want to connect my mac directly to the second ethernet becouse,and it's strange (please provide me an answer), if i try to send file from my macbook to the nas, (nas linked with 1st port to switch and mac over wifi/lan is the same) the speed was very slow...about 10MBs...the solution is to link the mac directly to the nas (or undestard why the speed was so slow)
Thanks in andvance!
PS my nas is a Qnap ts-253A 4gb

Re: How to use 2nd Ethernet port
Ok...solved!There was probably a problem with the switch...infact moving the ac cable it was restarting itself,maybe wrong contacts i don't know (here i've created a home-made-poe for power switch and the Fonera 2100 at the same time) ...i've spent just few minutes on testing and soldering and now it works.yesnoj wrote:Sorry for the noob question,but i've a similar problem.I use with success the 1st port with static ip.The nas is correctly linked to the switch and can download files ecc ecc.

With one card on 192.168.1.100 linked to the switch and (eventually for direct link) the second card on 192.168.2.200 with DHCP enabled.I've tested another time after solved the first issue,the speed on communication using the network and it is always slow (10/12MBs ) ,while connecting the macbook directly on 192.168.2.200 via ftp is 10 times faster.Still don't know why,if someone can explain me...is appreciated!
Thanks

Re: How to use 2nd Ethernet port
Very typical numbers ... the "slow" one seems to run on Fast Ethernet mode only - something borked with the home-brew PoE switch implementation, ie. one or two cable pairs no longer workable.yesnoj wrote:.I've tested another time after solved the first issue,the speed on communication using the network and it is always slow (10/12MBs ) ,while connecting the macbook directly on 192.168.2.200 via ftp is 10 times faster.
Use a direct cable connection, a known working GbE switch and cables.
Double check that TCP/IP subnetworks on the interfaces are not overlapping.

Re: How to use 2nd Ethernet port
Hi,
I have a TS 251+ and have been using the NAS happily for a year or so now. The LAN connection to my router (hence to the house) here is terribly slow especially upload (0.6 Mbits/sec) so backing up all my data through Idrive is particularly poor. I have setup a network on through my phone (mobile data) and wireless repeater/bridge using the 2nd LAN port which shows up on the NAS and which i have connected to from other devices to test. The internet is much faster (not too fast 7 Mbits/s as of tonight). What i would like to do is choose manually or whatever which internet source is chosen so that for backing up on big occassions i can use the mobile data (i have a work phone so the data is unlimited) but generally for incremental back up it can stay on the home network. I want to know how i choose LAN2 for all downloading and uploading the NAS does. Can this be done?
Cheers in advance
