Routing through non-WAN interface

Hi Everybody,

First of all Happy new year for those who celebrated!

Now to the topic. I use VM appliance of pfsenese with version: 1.2.3-RELEASE.
I have 3 interfaces - WAN, LAN and OPT1, addressed respectively in this way:
em0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500
inet 5.5.7.243 netmask 0xfffffff0 broadcast 5.5.7.255
em1: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500
inet 5.5.6.93 netmask 0xffffffe0 broadcast 5.5.6.95
em2: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500
inet 192.168.255.3 netmask 0xffffff00 broadcast 192.168.255.255

The important part of the routing table looks like this:

Destination Gateway Flags Refs Use Netif Expire
default 5.5.7.241 UGS 0 19890 em0
5.5.6.64/27 link#2 UC 0 0 em1
5.5.6.92 00:50:56:b7:00:64 UHLW 1 624 em1 1154
5.5.7.240/28 link#1 UC 0 0 em0
5.5.7.241 00:25:45:38:79:d7 UHLW 2 844 em0 557
192.168.0.0/24 192.168.255.1 UGS 0 89 em2
192.168.10.0/24 192.168.255.2 UGS 0 0 em2
192.168.255.0/24 link#3 UC 0 0 em2
192.168.255.1 00:0c:42:2e:c8:6d UHLW 2 0 em2 515
192.168.255.2 link#3 UHLW 2 0 em2

So what is important for me is to reach 192.168.0.0/24 and 192.168.10.0/24 through the OPT1 interface and not through the WAN. That's why I gave static routes. And those networks are reachable from the pfsense machine itself, but NOT through the LAN network, connected behind the LAN (em1) interface.

On the other hand, all destinations, the LAN network needs to reach through the default route are reached successfully.

Can somebody help me by telling me how shall I make the requests from the LAN, destined to the 192.168.x.x static routes to work?

Thanks in advance!

SOLVED!

The 'Gateway' field should be filled in the Interfaces->OPT1 configuration section. Then just add WAN and OPT1 interfaces in Load Balancing mode (Services menu). Thus, all incomming packets on the LAN interface also obey the defined static routes.

Cheers!
