I have two ASA 55210 were one ASA is working fine , while second ASA has similar configuration of ASA 1 but we have problem in reverse traffic ,
My TCP connection is established from inside interface to outside interface , while the traffic goes out of outside interface and reaches the destination severs and application services , the return traffic is coming back to ASA firewall on outside interface and get excuted in IOS but its not completing with full TCP connection .My inside interface is not getting any reverse traffic to source IP which has initated the session . So no application is working from this Firewall .
For eg : AT&T MTS application which initates traffic from inside interface reaches the destination server and corresponding application services , while return traffic come back to my firewall outside interface and its allowed inside IOS , but we cant see any TCP get session completed from source which has initated the traffic .
Trouble shooting Done :1) Permitted IP ANY ANY on both Inside and outside interface , But same response ,
2) IOS which is running in ASA 1 and ASA 2 is same IOS , IOS also copied from ASA 1 to ASA 2 but no change.
Help me on this
MY inside INTERFACE of my firewall is not receiving any return traffic whichever the session initated from same interface .
