[suse-security] SuSeFirewall2 problems after reconnect (Suse 8.2)
Date: Tue Jun 24 2003 - 03:10:47 CDT
(This message was also postet in the alt.os.linux.suse newsgroup)
after installing Suse 8.2 and the latest updates I'm having some troubles
with SuSeFirewall2. My ISP disconnects my DSL-line every 24h and rp-pppoe
then automatically reconnects the line.
Now if an application that is listening on highports (>1024) is already
running before the reconnect takes place (e.G. mldonkey and hts), after the
reconnection SuSefirewall2 is dropping packets to these highports which
were accessable before the reconnection.
E.G. mldonkey then only gets lo-ids and I can't access my machine via hts
which is running port 4xxx. I'm not sure if SuSefirewall2 blocks all
highports or only these on which the applications are listening. Lowports
aren't affected. I still can connect to Apache and SSH after the reconnect.
If I close these two applications mldonkey and hts, restart the firewall and
then restart the applications, everything works fine until the next
reconnection takes place. Using Suse 8.1 I had no problems.
In the SuSefirewall2 config file all highport are enabled. (I can post the
whole config file later on if somebody needs it).
Is this a new feature/bug? Can I get rid of it somehow?
Best regards, Volker
