cisco 2651XM router
connected to internet by wic1-adsl card
as a beginner my experience of firewalls amounts to clicking the 'basic' option in SDM, choosing medium level and letting the wizard create firewall rules. I like that the medium level firewall blocks intrusive ads in web pages but it also knocks out the sip trunk running on my router and I can no longer make or receive pstn calls. Attached is the config created by the basic firewall wizard. I have spent some time messing with the config, both in SDM and in the cli, trying to get the sip trunk back on but I've had no success. Can anyone tell me which commands should I delete so my sip trunk will still work? - without weakening the firewall too much of course...
thanks for any advice.
