Connect two Routers through WAN [SOLVED]

Eduard

Hello folks,

I recently installed a pfSense machine in my home lab and I ended up having 2 networks and it's exactly what i wanted but can anyone give me some advises what should I set in the routers so that computers can see each other?
I know about the routing tables but I need some help…

That's my network set-up:

WAN - ISP Router DHCP (192.168.1.254)

| |

| |
| |

** pfSense Tomato WRT54GL**

(WAN: 192.168.1.67) (WAN: 192.168.1.66)

(LAN: 192.168.2.1) (LAN: 192.168.3.1)

Thanks in advance. ;)

pfSense System->Routing. Add a gateway on WAN, 192.168.1.66. Add a route to 192.168.3.1 through that gateway.
Firewall Rules, WAN - add a rule pass source 192.168.3.0/24 destination LANaddress.

Then do some similar thing in Tomato.

Hi Phil,

Thanks a lot for the quick answer.
I did everything you said but I really don't know if I can add a gateway in Tomato, I successfully added a new static routing table on WAN but I can't find anything related to gateway settings except the main WAN port that now is set to DHCP.
The router at the moment it's in gateway mode, I should change it to router mode or not?
I'm a bit confused about these settings…Sorry but I'm not good at this stuff! :P
Hope you can help me to figure it out.

Thanks for your patience.

Sorry for the double post but I played till now with routing tables and firewall settings but still no luck.
If I understood something this should be correct:

Tomato 1.28 WRT54GL

Operating Mode: Gateway

Static Routing Table:

Destination Gateway Subnet Mask Metric Interface Description
192.168.2.0 192.168.1.67 255.255.255.0 0 WAN pfSense

Startup firewall rules:


iptables -I INPUT -s 192.168.2.0/24 -j ACCEPT
iptables -I FORWARD -s 192.168.2.0/24 -j ACCEPT
iptables -t nat -I POSTROUTING -s 192.168.2.0/24 -d 192.168.3.0/24 -j ACCEPT

I tried also to disable the firewall completely using a script that I found and finally from a workstation under pfSense i can ping at least the WAN IP of the Tomato Router but for some reasons using this script I lost the WAN connection…
I don't know seems that the static routing tables aren't working at all, maybe I should try a different firmware or maybe would be easier to buy another router and using it as gateway between the two networks?

Solved with an OpenVPN tunnel :)

I had hard time to make it work but seems very responsive and stable.
