Problem establishing gateway for VPN

[tcica]

Hi-

I'm having a strange problem with 2 Unix boxes. I have 5 servers (3-Win2003, 1-SCO 5.0.5, 1-SCO 5.0.6). Until about a month ago, I was able to access all five servers through a Sonicwall VPN from my house. Now, when I establish a VPN, I can only ping the 3 Win2003 servers, and I cannot ping either SCO box. I can, however, ping these servers from any machine on the LAN. I'm using SonicWall VPN and have made no changes to this software. The only other changes I made to the SCO boxes recently were a couple of 5.0.x patches.

All I'm trying to do is telnet into the 2 SCO boxes, and this never used to be an issue. I can telnet from any machine inside the LAN.

The Sonicwall VPN appliance is 192.168.0.1 and netstat -rn for one of the SCO boxes (192.168.0.100) returns:

# netstat -rn

192.168.100 192.168.0.243 UG 0 0 net1
224 192.168.0.100 UCS 0 0 net1

Any help would be appreciated.

Thanks,

At first glance, it looks like the subnet mask might be wrong.

Take a look at this entry:
192.168 192.168.0.100 UC 1 0 net1

Do "ifconfig -a" to see the MASK and BROADCAST values.
If that appears incorrect, review these files:
/etc/tcp
/etc/default/tcp

Thanks for the quick reply.

ifconfig -a returns:

# ifconfig -a
net1: flags=4043<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.100 netmask ffffff00 broadcast 192.168.0.1

/etc/tcp has the following entries:

NETMASK=
BROADCAST=
route add default 192.168.0.1

/etc/default/tcp has the following entries:

route add default 192.168.0.1

NETMASK=255.255.255.0
BROADCAST=192.168.0.1

I'm not seeing anything off, but I'm not a Unix expert.

BROADCAST=192.168.0.255

Hope This Helps, PH.

the mask on the third route is wrong....
it should be
192.168.0 192.168.0.100
