Hello,
I'm running RedHat 5.2 with IP masquerading in attempt to provide
internet access to other computers in our office. As of now we do not
have our dedicated data line yet so the linux box is using a modem to
establish a ppp connection. It also has a NIC connecting it to the rest
of our internal network.
The firewalling & masquerading rules have all been working for me but
then all of the sudden for no real reason nothing works anymore more.
We are using internal ips of 10.x.x.x
Also on our network are Novell fileservers and an NT server which acts
normally as a DHCP server.
The computer I am testing the linux gateway with is set with a static ip.
The client computer seems to work fine with internet access for a while,
but then, perhaps after a few momements of inactivity, i'll try to do
something again and nothting will happen. So i attempt to ping an
externeal ip... that returns "network unreachable" or some other similar
message. I then check to make sure I can ping the gateway, that works
fine, I check to see if the gateway can ping the client, that works fine,
I ping a couple other things with the gateway to test connectivity and
all is well. Then I try pinging from the client again and things work
again? It seems that by pining the client from the gateway some
connection is re-established or something. I'm not quite sure what is
going on. If anyone has any insight on this I'd greatly appreciate it,
or if there is any more detailed information I can provide let me konw.
Thanks.
Sincerely,
Josh Estelle
