HI Guys,
I have to permit RTP traffic from internal network to other organizations (under different management) on gateway devices (routers, switches). I am curious to know if there are known attacks/threats when upd range 16384-32767 is permited. RTP source/destination can be desk phone or PC with softphone. If yes then can we configure gateway routers/switches to protect from these attacks. We have cisco 7200, 6500, 3550, 3560, 3750 switches as gateway devices. One more quick question are there only two ways (NBAR and ACL with udp range) on routers/switches to identify/match RTP traffic? I know Firewalls provide feature like inspect, AGL etc to dynamically identify RTP ports by inspecting control traffic. Your input will be highly appreciated Regards _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
