What is the explanation of Reset-I and Reset-O in the FWSM Teardown log messages.
On the outside of FWSM, the ACE bridges two VLANs lets says 5 & 6 and IDSM bridges 6 & 7. Can ACE and/or IDSM send a Reset which I see in the FWSM log.
Also how would a Reset-I/O show if it is coming from a DMZ of the FWSM.
Reset-I means FWSM recieved a Reset from the inside.
Reset-O means FWSM recieved a Reset from outside.
These resets will be occurring because the resource you are trying to
connect to is not allowing a connection or is forcibly closing an established
FWSM generates these messages when its cleaning up the state table (Remember Client/server has alreday disconnected the connection using RST)
You should gather captures from both relevant interfaces on the FWSM and try to figure out which resource is the source of these RSTs. You
can do this by using SPAN sessions.
