i have a fwsm running in multiple mode,

there are 2 contexts context a and context b.

both contexts are running in transparent mode.

i have a live communication server(SIP server using standard ports) on the inside on context b and my lan is behind inside interface of context a .

i have allowed the ip addresses on lan network on the outside interface of context b.

now the problem is that the all the hosts that are in the same vlan of the server are able to login while the hosts on my lan are not able to login.

if i see the loggs on the fwsm, it shows build connections with the server(on port 5060) but also shows that my host on the lan is denied access to the bvi interface ip address on context a using port 445(AD) and 138(netbios).

Whats could be the problem ?
