2 NIC with same GW

[555|STi]

Hi there. I need some help from you, guys.

Currently I have a server with 4 NICs.

• LAN
• WAN DHCP
• WAN STATIC IP: AAA.BBB.CCC.DDD
• WAN STATIC IP: AAA.BBB.CCC.EEE

I need to assign the same GW to NIC 3 and 4. The IPs are different only on the last octet. The IP assigned to the 4th interface is enabled to access a remote server, but the 3rd is the interface of the incoming connections, none of these can be changed.

How can I achieve this?

Thanks in advance!

when you say it is for remote access... is it really a WAN?

Yes, it is a WAN.

LAN
WAN1 - INTERNET PROVIDER 1 - AAA.BBB.CCC.DDD
WAN2 - INTERNET PROVIDER 2 - XXX.YYY.ZZZ.123
WAN3 - INTERNET PROVIDER 2 - XXX.YYY.ZZZ.124

Thanks in advance.

This cant work as gateways are bound to interfaces.

You can add the 2nd IP as an Alias IP to WAN2.
Then you can use outbound NAT to send the packets out the right IP.

Interesting! I'll try this!
Thank you!

Yeah, I was thinking the same, thank you!

I was in a hurry to make it work so finally I "cheated"... The solution I implemented was to use a router before the NIC.

Code: [Select]

ISP2 -> WAN2
ISP2 -> ROUTER -> WAN3
So, I assigned the needed IP to the router an then connected it to the WAN port in the firewall.

May not seem pretty, but it works.

Tanks to everyone!
