Hi Kerem,

Can you ping the lead hat box on the internal network?? If not:

#cat /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts

if that returns a 1 then

#echo > 0 /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts

#cat /proc/sys/net/ipv4net.ipv4.icmp_echo_ignore_all

if that returns a 1 then

#echo > 0 /proc/sys/net/ipv4net.ipv4.icmp_echo_ignore_all

Some other points? Is your vpn server assigning an address range on the same
mask as your RH box???

Can't see how the route table would affect anything. You ping an address if
its up its up. Is your RH box on the same mask as the vpn server??
