OK. This firewall routing table looks odd. I don't know if this is your problem, however (see below). Who or what is setting up these routes for you?
1. 192.168.13.1 0.0.0.0 255.255.255.255 UH 0 0 0 eth0 2. [ISP Connection] 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 3. 127.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 lo 4. 192.168.13.0 192.168.13.1 255.255.255.0 UG 0 0 0 eth0 5. 192.168.13.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 6. 0.0.0.0 [ISP Connection] 0.0.0.0 UG 0 0 0 ppp0 Line 1 seems to be pointing to the firewall machine itself. Why is it there? I haven't done point to point for a long time, so I cannot comment on your ISP connection Line 4 seems very odd. What does it do? Now, I do not use a hub. I have thin coax for my home network. So, I don't understand how hubs work. It seems to me that your firewall machine shouldn't have to get involved with laptop to workstation communication, but, I just don't know. I just had a similar problem to yours, except I had my two workstations on different subnets. (Look for my post about arp request not working on this list). By using tcpdump, I found out that that workstation two could find workstation one, but, when workstation one sent out an arp request for workstation two, the request was not getting to workstation two. I solved my problem, without understanding the cause, by manually adjusting the arp table on workstation one. SO, ping from one workstation to the other. Then run arp -n on your workstation(s), and see if the other workstation is in the table. There may be an incomplete listing for the other workstation. If there is not a valid listing for the other workstation, just run, on your machine 192.168.13.5: arp -s 192.168.13.4 00:10:5A:0A:BE:F7 and see if that updates your arp table. If so, fix the other workstation and see if that solves the problem. Joel Sun, Mar 31, 2002 at 10:04:08AM -0800, Thomas A.
