broadcast traffic

Unanswered Question
May 10th, 2007

This has been a kind of nagging question I've had for a while, why would netbios port 137 traffic from another subnet be trying to cross my ASA's inside interface. -> router -> p2p T1 -> router -> ASA -> Internet

the following gets periodically logged on my ASA

4 May 10 2007 11:45:52 106023 Deny udp src inside: dst inside: by access-group "inside_access_in" [0x0, 0x0]

I always thought layer 3 devices blocked this sort of broadbcast traffic??



I have this problem too.

Hi Bill is a directed broadcast. Have you turned these off under the router interfaces ie.

router(config)# int fa0

router(config-if)# no ip directed broacast
