I have just installed DSL 1.3.1 on an older NEC laptop. I am using a 3COM NIC and a 3COM modem both PCMCIA.

I have no problems with the NIC, but my modem is giving me a problem. I was able to setup Dialup and the modem dials out and connects to my ISP, but I can not get it to pass any traffic. I have tried PAP and CHAP athentication, and have tried dynamic and static DNS. Both connect but I am unable to connect to websites or PING external addresses.

Any ideas on what I could check or changes to make?

Thanks,
D10

Hi
Very often if you have both a nic and a modem the nic comes up first and becomes the default route to the internet even though you may not want that. When you dial out the default route does not change. To see if that is the case before you dial out type this at a shell prompt.

sudo ifconfig eth0 down

Then do your dialout. After you are connected you can then

sudo ifconfig eth0 up

and all should be well

good luck

Thanks for the reply that was it. I rebooted last night with out the NIC installed and all worked fine. Then I realized like you said by taking down eth0 before I dial out it works.

Thanks again.
