I have a linux alpine 2.6.1 with 2 network adapters and two windows hosts, one on each network. I cannot get host1 and host2 to communicate in both directions.
host1 <--> eth1 <--LINUX--> eth2 <-host2>
I can ping from : host2 to host1
host2 to eth1
eth2 to eth1
eth1 to eth2
eth1 to host1
But I cannot ping from eth1 to host2 or host1 to host2. Why??
All firewalls are disabled. Iptables on the linux shows ACCEPT ALL on input,output and forward.
Primaraly I should be able to ping host1 from eth2 because I can ping it from eth1.
I have of course enabled ip-forwarding.
Am I missing a static route?
