Just installed ClearOS on a VM hosted on esxi5.5. The VM has 3 nics. Here is my setup

nic0 WAN-----internet
nic1 lan-------10.0.0.0/24 network, clearOS as gateway on 10.0.0.254 - Network1
nic2 lan-------10.10.0.0/24 network, clearOS as gateway on 10.10.0.254 - Network2

Both networks have DHCP working and can communicate with internet just fine

Any system on Network1 can ping and system/ip on Network2. (Can RDP from Network1 to Network2)
Any system on Network2 cannot ping or connect to anything on Network1

I would like the clearOS box to be able to route traffic across these 2 networks and it seems to be working from Network1 as excepted.

Both networks are set to LAN, so from the network guide it should be able to pass traffic.

I tried setting a static route, but all I managed to do was isolate the networks. That could have been myself not knowing what I am doing.

I have seen a bunch of old articles about setting the iptables to allow this. I have no issue with this but I am confused on why it is working from Network1 to Network2 but not the other way around. Seems to me if they are both set to LAN then it should work both ways. So at this point I don't know if it is a firewall issue or a routing issue.


Is there a simple place for me to check or something simple to try before I go down the iptables route.

Thanks you
