Hi Fritz,
Perhaps your problem is your access on the firewall/router, try to examine
the access list and the NAT of your firewall/router, or
if your LAN is directly connected to a router (i.e. Cisco Router) try to
examine also the ip nat inside and the ip nat outside,
this is a part of security of a router.
God bless and have a nice day!
fyi,
Al

Thanks Jeremy!
No eth1 is connected to our network router.
Actually we are a company under a bigger company so I made our own simple
network to be able to control our connection better.
{company_child local lan -- linux } -- company_parent router and own lan --
internet
The ones in the brackets are the ones we have control of.
So in this sense we are making our own small network under a bigger
network.
Thanks again!
