I have a network of WinXX PC's with a single Linux box acting as the gateway/firewall/dhcp server/e-mail server/etc. My Linux box connects to the ISP via 128K ISDN dial-up line (too far away for DSL and cable is N/A).
When I first connect the Linux box to the ISP, I can: 1) Use the Linux box to traceroute to everything (the ISP blocked ICMP so I can't ping outside their network). 2) Use the Linux box to browse the web (using Lynx). 3) Use the WinXX PC's to browse the web to "some" sites (google, domains hosted by ISP, etc.) When I first connect the Linux box to the ISP, I can not: 1) Use the WinXX PC's to tracert beyond the first two hops, Linux box is first and the ISP's router is the second. 2) Use the WinXX PC's to browse the web to anything "big" such as Yahoo!, ABCNews, FoxNews, WeatherChannel, etc. After a while (sometimes 5 minutes, sometimes 20 or more) I begin to lose some functionality. Such as traceroute from Linux to the world or pinging the ISP's router, etc. The ISDN Terminal Adapter (i.e., modem) sends the requests, the SD light goes on, but never receives a reply, no RD light. I've been experiencing this problem for the last week to 10 days. Does anyone have any thoughts as to what might be the cause? I've replaced some hardware including the hub and cabling and I've tried using an analog modem but the same problem persists. The Linux box has been running for a very long time without any changes. (For those of you heavily in the Windows world, a user rebooted the Linux box the other day to see if it would fix the problem but it, obviously, didn't.)
