SuSEfirewall2: Setting up rules from /etc/sysconfig/SuSEfirewall2 ... if i run "while true; do iptables -L -n | grep 53; done" while activating the shared connection i see the iptables rules actually appearing for a second or two 2. problem : ip forwarding is disabled /proc/sys/net/ipv4/ip_forward is set to 1 briefly, then set back to 0 (possibly by firewall scripts again ?) similarly, if i run "while true; do cat /proc/sys/net/ipv4/ip_forward | grep 1; done" while enabling the shared connection, i can see it being set to 1 briefly --------------- if i set same iptables rules as networkmanager and enable ip forwarding, shared connection works w/o any issues Reproducible: Always -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
