I have a SuSE 6.1 box acting as my internet gateway and mail server. 'ipchains' is set up to allow communications from windows clients to the net and visa versa. Windows is set up to use my ISP's DNS servers. If the linux box is connected to the internet then windows will boot fine, although if it's not connected, windows will hang for several minutes after logging on. I presume this is a problem with DNS. I have tried to get round it by setting the linux box up as a DNS server and getting windows to use that in preference to any other DNS, although this hasnt solved the problem.

Better late than never... (although I hope you have it fixed now). Two things I might try to track down the problem: 1) Temporarily enable packet logging for all your rules, switch on a Windows computer and check the kernel packet logs to see what packets are being sent. 2) The alternative method is to use a program like iptraf or tcpdump to get a log of all packets received at the linux gateway. You can store the output in a file. Bye, Chris -- __ _ -o)/ / (_)__ __ ____ __ Chris Reeves /\\ /__/ / _ \/ // /\ \/ / ICQ# 22219005 _\_v __/_/_//_/\_,_/ /_/\_\
