Problems with Newsgroups and FTP

Everything was working fine, then trouble strikes, not sure why.

When trying to download from newsgroups I keep getting "general network failure" in my new group software.

I tracked it down to the firewall but I'm not sure what's going on, or more specifically not sure why connections are getting shut so soon.

Quick sample log

Re: Problems with Newsgroups and FTP

Oh yes, and inbound FTP works fine but when uses try to use FXP it fails, but was working before without problem.

Re: Problems with Newsgroups and FTP

try capturing the traffic at the outside interface and check if any packets are comming back from the news servers (maybe FINs or RSETs).

Your can put a sniffer at the outside or enable capturing on the PIX.

To enable capturing on the pix (6.2 or higher required), enter the following commands:

capture out interface outside

After entering this command, you can see the captured packets with a web browser using this URL:

https://ip-address-pix/capture/out

Make sure you have web access to the pix and that the webserver is enable on the pix:

http server enable

http your-pc-ip-address 255.255.255.255 inside

Re: Problems with Newsgroups and FTP

I don't see any traffic leaving my network for the mail server.. nor do I see it in syslog anymore.. quite odd..
