Hello,
I have a transparent Linux firewall, now running slackware with kernel
2.2.13.
The firewall works very nice, and i get quite high transferrates, but
sometimes, almost at random, the firewall stops routing, one or all of
the machines looses Internet connection, and cannot ping any machines
on the other side.
Im quite bothered of this since i cannot find any fault, and i cannot
find any answer of why just some machines looses route sometimes, and
other machines another time. The loss is from 30 minutes to 2 hours,
and after that everything is normal, even when i was not touching any
of the machines.
The Linux firewall can ping all hosts inside and outside, and if i use
iptraf or an other stat program, it will show that 0 tcp packets is
send or received.
The setup is
/proc/sys/net/ipv4/ip_forward = 1
/proc/sys/net/ipv4/conf/all/proxy_arp = 1
my gateway is 2xx.xx.xx.129
eth0 nic is 2xx.xx.xx.156 (internal)
eth1 nic is 2xx.xx.xx.130 (external)
and the machines internal is from 2xx.xx.xx.131 to 2xx.xx.xx.155
well actualy .128 to .158 or something.
and the route is:
2xx.xx.xx.129 0.0.0.0 255.255.255.255 UH 0 0 0 eth1
2xx.xx.xx.128 0.0.0.0 255.255.255.224 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 2xx.xx.xx.129 0.0.0.0 UG 0 0 0 eth1
