First time on this forum. Big fan of the YouTube channel so figured here would be a good place to ask for some thoughts.
Basically, I think I am being an idiot. I’m missing something obvious but for the life of me, I cannot find it.
Running Untangle V16.2 on a Z4 appliance.
eth3 is for the WAN going directly to the internet.
eth0 LAN 172.16.0.0 Gateway 172.16.0.1
eth1 Test LAN 192.168.70.0 Gateway 192.168.70.254
Both LAN’s can go to the internet, all good. However, I can’t seem to get traffic to route across to each other. I need them separate for a specific requirement. Using VLAN’s will not be suitable for this project I am working on.
I have followed the Untangle website which just says to uncheck NAT on each LAN interface and all should be good… It ain’t. I have tried adding routes but I get conflict alarms.
I have seen other forums suggesting Filters etc. but this seems overly complicated and unnecessary for what I see as a simple issue. It’s routing 101 but I think I have looked at this problem for so long, I can’t see the wood for the trees.
Any advice would be much appreciated.
