ASA Stops routing over "inside" when SIP traffic hits it
Having an odd problem and wanted to see if anyone else has run into this issue before.
Currently testing out a remote office solution with an ASA 5505 running 7.2(4) as the temporary head-end unit (will be replaced with a 5510 shortly). The remote user is connected via L2L tunnel, and for the most part everything is great. However, whenever the user connects to a video conference, utilizing SIP, the "inside" VLAN on the switch will stop routing ALL traffic, without noting anything in the logs. I have to reload the ASA to restore the traffic flow. I have a console hooked up set to level 7 logging now on the ASA to catch anything, but I'm curious to see if anyone else has run across this or anything similar?
