nic active, but can't ping beyond loopback


rh9, dell poweredge 1750, 2 built-in nics (broadcom tigon 3 according to rh), only one (eth0) connected.

ifconfig says:

eth0 is UP, shows RX/TX, no errors, etc ... correct def gateway and ip address and mask

also shows interface

lo, loopback addr, etc .... LOTs of RX/TX (30101), no errors.

I can PING my address, ping loopback addr, but cannot ping default gateway, or any device on this subnet, or anything else. Other devices cannot ping this address, either.

The switch shows a link. The nic link light is on

I looked in "service configuration app" and it showed iptables (despite that I had said "no firewall" during install) running, so I shut that down. Also showed ISDN (huh? Where would that have come from?) which I shut down.

In the network config tool it shows the nics, shows the correct ip info, dns info, etc ... but when I edit the hardware info, it does say "unknown" for IRQ. Is that possibly the problem?

Suggestions how to go from here?

ping error is:

"from [my address] icmp_seq=1 Destination Host Unreachable"

I saw another post that suggested doing:

route add default eth0, so I tried that ... no change.

"route" shows the correct default gateway, etc ...

what does "/sbin/iptables -L" say? try doing a "/sbin/iptables -F" and then try pinging an ip address in your network.

target prot opt source destination

chain FORWARD (policy ACCEPT)
target prot opt source destination

chain OUTPUT (policy ACCEPT)
