When I try to ping, the modem dials, and the async int comes up, etc. So everything seems to behave normally when I ping. It just doesn't receive any echo replies. I even debug ip packet on router B (the dial up server), and I see that packets to yahoo are indeed being forwarded correctly. So the modem is working, the dialer-list is correct, the IP routing is working. But apparently replies never come back. Weird, really weird. Which is odd because I can ping www.yahoo.com from router B just fine. And, like I said, I can trace Yahoo from A with no problem. I just cannot ping yahoo from A. But A can ping all interfaces of router B. And yes, I have tried using IP addresses, without DNS names. Same result. I can do everything except ping from A. By the way, I like the idea of "debug serial killer". But of course, it only works if you have previously typed the command "hostname charlesmanson" ""ElephantChild"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > On Tue, 29 May 2001, NRF wrote: > > > I got this weird situation here: > > > > I got router A that dials into router B through an analog modem (async > > lines).
