Hi,
i have here a dsl hardware router which is also a vpn gateway. Behind it a FC3 box as nat gateway for LAN PCs. Sometimes the FC3 seems to stop forwading packets to outside. Probably only to other private subnets via VPN. Had no chance to test this. But noticed another problem: I can not ping from the FC3 box or behind to any internet host.
Network setup:
(I-Net) --- (Hw router + VPN ) --- (FC3 NAT) --- (LAN)
Internet access from LAN works. I can ping f.e. fedoraforum.org from the dsl router. but not from the FC3 box. I connected another Computer to the dsl router and it worked. I watched the iptables log and "netdump -i eth1 icmp" (eth1 is the external nic). I see the outgoing ping request but no reply. Ping to the dsl router, LAN hosts or hosts through VPN works. I tested to disable the firewall without result. selinux is disabled.
What else could i try?
Thanks.
