Strange default router

[Serguei Tokovenko]

Hi.I have multihome system with 2 interfaces. But my default entry in routing table doesn't work.
Systems is HP-UX B.11.23 U ia64.

Interfaces:

# ifconfig lan0
lan0: flags=1843
inet 80.67.208.82 netmask ffffff80 broadcast 80.67.208.127
# ifconfig lan1
lan1: flags=1843
inet 10.255.254.132 netmask ffffff80 broadcast 10.255.254.255

Routing table
# netstat -rn
Routing tables
Destination Gateway Flags Refs Interface Pmtu
127.0.0.1 127.0.0.1 UH 0 lo0 4136
10.255.254.132 10.255.254.132 UH 0 lan1 4136
80.67.208.82 80.67.208.82 UH 0 lan0 4136
80.67.208.0 80.67.208.82 U 2 lan0 1500
10.255.254.128 10.255.254.132 U 2 lan1 1500
80.67.208.128 80.67.208.1 UG 0 lan0 0
127.0.0.0 127.0.0.1 U 0 lo0 0
default 80.67.208.1 UG 0 lan0 0

But.

# traceroute -i lan0 213.180.204.8
traceroute to 213.180.204.8 (213.180.204.8), 30 hops max, 40 byte packets
1 80.67.208.82 0.132 ms !N 0.028 ms !N 0.027 ms !N

i.e network unreacheable.

can you ping the default router at ip address 80.67.208.1 ? or if ping is disabled, can you telnet/ssh to it and get any response ?

If not,

route delete default 80.67.208.1

then

route add default 80.67.208.1 1

note the 1 at the end. That may be something that you are missing to start with.

The route definition looks fine to me. Is your router configured to not respond to ICMP requests? Is your router on the same physical network? Does it show up in your arp table (arp -a)?

Hi,

Looks like you are trying to ping a public IP. 80.67.208.1 is a firewall interface by any chance? If so, the firewall may not be allowing ICMP replies.
