What about if I wish to have masquerading from the LAN interface to the OPT1 interface?
I have a Soekris net4501 system with 3 network interfaces.
The first network is the LAN, the second one is the WAN and the third one is another network (OPT1) which the LAN clients needs to connect to.
I can reach the WAN from the LAN, but I can't reach any host on the OPT1 from any LAN client.
The OPT1 has 172.18.67.252/24 as IP address, and I can ping an host (for example 172.18.67.254) from the m0n0wall web interface.
From a LAN client which is using m0n0wall as default gateway I can ping the OPT1 IP address (172.18.67.252) but I can't ping the 172.18.67.254 host.
No log is shown on the firewall logs.
Could you help me to found the problem?
Thank you very much!
