I havijng problems with cisco asa 5520. here is the setup. The asa has an inside, outside and dmz interface (dmz has sub interface and trunked to a dmz swtch- cisco 3750 - layer 2 only ) connected to the dmz firewall. the dmz has a mgmt address of 10.10.40.250. the dmz switch has two wireless controllers. one of them have a mgmt address of 10.10.50.250 and DG of 10.10.50.254 on the cisco asa. the other one has has a mgmt add of 10.10.60.250 with a DG of 10.10.60.254 on the cisco asa. now i can get to wlc 1 (10.10.50.250) from the asa (10.10.50.254) and vice versa without any problems. but access to asa (10.10.60.254) from 10.10.60.250 is intermittetnt and the other way around is fine. so i created a subinterface on the dmz swtch with 10.10.60.251.. however i cant ping 10.10.60.254 from the l2 switch (dmz switch) even with a source of 10.10.60.251. (this is directly connected to the firewall with trunk and subinterface)
Ip default gateway of switch 10.10.40.254
ping 10.10.60.254 from 10.10.60.250 is intermittent
ping 10.10.60.254 from 10.10.60.251 - cannot ping (sometimes intermittent)
ping 10.10.60.250 from 10.10.60.254 is fine
ping 10.10.60.251 from 10.10.60.254 is fine
i can see the counters on the asa subinterface increase (allowed icmp on the whole dmz interface)
