Some IPMasq questions...

Hey guys, this is probably gonna be a simple answer, but after reading through a few docs I haven't seen anything specific on this, so here goes.

I'm running Coyote on a 486 used as a router. I've got two static internal IPs assigned to my two other machines by their respective MAC addresses, and that works, both machines have internet connectivity, everything is grand in that respect. I also run two servers on one of the machines, a proxy server and a remote admin server.

Problem: Even though both machines have addresses on the same subnet, are members of the same workgroup, and have connectivity to the outside world, I can't connect to one from the other within the network. I can ping them from the router but not from the machines themselves. File/print shares no longer show up (one is Win2000, the other NT 4), and using the remote admin software's client from within the network pointing it at the internal IP does nothing but time out on each connect attempt.

Are there default rules for restricting internal traffic that I'm missing here? Both machines have their hosts files edited to reflect their current IPs and names, if that makes a difference.

Thanks for any suggestions...

Are you using any firewalling (script)? Is your ICMP disabled??

[Charliey]

Are they connected through a hub or the server?

[Xayd]

Connected through a hub, no other firewall besides the router itself (no add-on firewall scripts running, just NAT).

ICMP packets aren't being restricted, I can ping out from each machine and the router, traceroute out from each machine and the router, and ping back to the router from outside.

Any other ideas?

Well, I almost hate to admit it, and thanks everyone for the help, but I just pulled the biggest DOH I've ever pulled when throwing together a network.

Here's a quote from me, from experience...

"When networking, it's a good idea to actually LOOK at your cables before just plugging everything in and hoping for the best"

"If you plug the wrong damn cable into the uplink port, expect complications"

In summation, everything works. The second machine was sitting on the uplink port, not the router, but since the router had crossover cable they were still getting DHCP, but not each other ;).

Well you sure stumped me with that one .. anyhoo glad it all works.

Simply a matter of color coding, hehe. The cable going to my primary machine is black, the cables going to the router and my server are both white, and virtually identical. It never even crossed my mind until I went to disconnect the router from the hub to see if that made a difference in the other machines being able to see each other, and when I yanked on the supposed router cable, the server moved...that's when I realized it ;).

The funny thing is, I fooled with the TCP/IP settings in both machines and the DHCP settings in the router for two days before I actually looked at the hub and saw the problem right before my eyes. Blargh...
