try to ping and traceroute from your clients.
take a look on your eth1 network trafic with tcpdump while pinging 192.168.92.1 from your other stations. you must see icmp requests and icmp replies
simply run tcpdump command, with no arguments specified. it will start listening on all your interfaces. if your eth1 sees some icmp packs, tcpdump will display them.
take also a look to your pings, especialy the answers or non-answers:
if host is unreachable, network exists, but do not see host on the net ( or ping requests dropped by a firewall)
if network is not found, there is a pb with your local net or distant net
ping both interfaces on your router. both must answer
kra-pul
if not better, give the results of your tests (pings, traceroute, tcpdump)
