Can't ping WAN

Hi,

My configuration is following:
HP 9000/745
HP-UX 10.20

I can't communicate over our WAN, LAN only. Here are several details:
# ifconfig lan0
lan0: flags=863
inet 10.250.29.29 netmask ffffff00 broadcast 10.250.29.255

# netstat -r
Routing tables
Destination Gateway Flags Refs Use Interface Pmtu PmtuTime
hp4062II localhost UH 34 3358159 lo0 4608
localhost localhost UH 0 396 lo0 4608
default Default_gateway UG 8 718837 lan0 1500
10.250.29 hp4062II U 0 0 lan0 1500

# lanscan

4/0/4 0x080009E4694C 1 UP lan1 DOWN 5 ETHER Yes 52


I can talk with computers with IP 10.250.X.X (local network), but not with computers IP 10.X.X.X. Can you help me with that?

Can anything on the 10.250.X.X range talk to computers on the 10.X.X.X. range?

If not it could be the routing config on your router.

Re: Can't ping WAN

Have you only tried pinging other computers on the WAN, what about telnet or ftp.

ICMP may be blocked on your wan router to stop denial of service attacks.

Guys,

this is not a network router issue, there are hundreds computers communicating each other. This is only the HP-UX setting issue. I don't know what else has to be setup and how. This computer was used at other site with different net configuration.

I am attaching network start script.
Btw, this service is shown as failed during startup.

Re: Can't ping WAN

what's Default_gateway.
why don't you have the lan1 interface configured in the attached file.
It works for me (tm)

Bill,

Defaul_gateway is defined in /etc/hosts and is correct. Netmask is 255.255.255.0 so I would not be able to ping telnet or ftp or whatever to 10.250.X where X is other then 29. It originaly came with this so I left it as was. Just changed ip in /etc/hosts.

It's an old HP and lan1 is BNC type, is not used.

Re: Can't ping WAN

Is it possible that the router administrator has turned off ICMP as a response to blaster virus?

run a traceroute command and see where it stops.

Re: Can't ping WAN

Guys,

I applogize, it's a router restriction. There are several W95 stations with disabled access to internet. I got an IP from this range.

Sorry,
Andrej
