Ric, I'm using RH 8.0 and doing the exact same thing. I use the RH8.0 box as a router for a mixed Windows/Linux network. It also has iptables, DNS and SSH and everything works fine - the problem is not RH 8.0.
If you can ping both interfaces on the router box from the third box then routing is working ok on the router box. If the routing is working ok, then it has to be the wrong gateway address (I'm assuming you've checked the NIC, the wiring, subnet mask, etc), that's the only things it can be.
In this case, there's no firewall (don't need one). So iptables is not running. So that's out.
The nics both work, although only one has an address.
So, what's different:
(pardon me while I think)
#------
At home:
DSL into card one of the server.
Card two of server to switch
Firewall between the cards.
All other clients plug into the switch.
Both cards have an IP. The outer one has an official IP, the inner one is of the 192.168.0.0 variety.
Both cards IPs are listed on the DNS server.
All the clients are name served by the server.
All clients list the outer card as their gateway.
# ---------
k.. simple enough
#---
At the office
e-net line from wall to card 1
crossover cable from card 2 to machine two. (no hub, or switch).
Card 1, and machine 2 both have registered IPs, served by company dns service.
Card 2, has the 192.168.0.0 variety, and is not listed anywhere. But, since machine 2 plugs directly into card 2, I shouldn't need to list it anywhere. The card is active.
ip-forwarding is turned on.
There is no firewall, so iptables is turned off. (no rules means everything allowed(?).
Machine 2 uses address from card 1 on server as gateway.
The server can ping both of it's interfaces.
The server cannot ping machine 2.
Machine 2, cannot ping the server, neither by name, nor address.
# ------
The thing is plugged straight into the machine, and they can't see each other.
What am I missing?
uh...
...
/etc/hosts.allow
ALL:local (?) or such.
nah... /etc/hosts.allow currently has:
ALL:ALL
That could cover that.
Should I list the second NIC in /etc/hosts on the "server"?
I'm stumped. It should work.
HELP!
;)
Ric
I've missed something really obvious. This is to simple to screw up.
