Dear Shorewall Users, I use Shorewall 1 year ago, and everything is so good (Thanks to Mr. Tom Eastep ). But now we have trouble with Yahoo Instant Messenger, we can not connect to Yahoo IM. And I check by ping from Firewall (Shorewall ) to scsa.msg.yahoo.com and all packets lost. In past time, I did not have this problem. Any idea ? Thanks a lot, -- Best regards, Huy mailto:huytu@hcmc.netnam.vn

Any idea ?Be sure that you have a rule such as: ACCEPT fw net udp 33435:33535 then try a traceroute to scsa.msg.yahoo.com from your firewall. Since you can''t ping to that site, there is likely a problem somewhere between your firewall and there. -Tom -- Tom Eastep \ Shorewall - iptables made easy AIM: tmeastep \ http://www.shorewall.net ICQ: #60745924 \ teastep@shorewall.net
