I tried to move to the 2.4 kernel with great success apart from my external ISDN modem will not respond. Followed all instructions and even asked another question on ee. I've now given up and moved back to 2.2.12-20. The modem respods properly but my ip masquerading seems to have gone a bit funny....
I can ping the linux server and ping through it to sites on the web but I can't use any other protocol. DNS, telnet, http etc all don't want to connect even direct to the server it's self, which is running named, a web server (orion) and obviously inetd for telnet et al.
I have upgraded to RH7.1 but downgraded back to the old 2.2 kernel since I can't get the modem to respond, which is when the problems started.
Any ideas would be fantastic. Thanks for your time,
