Hello folks,
I am new to FWSM and looking for some help to fix the outbound connection from one server in VLAN 20 (10.120.20.90) to outside.
Following are the ACL found in the FWSM and connection status when i telnet from the box (10.120.20.90) to outside IP 99.87.209.150 at port 25
Please help me to fix this.

I cleared the xlate and able to connect.
Could anybody tell me what could be the issue? Did anybody expereienced any kind of issue earlier.
Thanks,

Hello Habee,
Does not make sense unless you are getting out of ports in order to perform the PAT translation to the outside interface.
Can you do a show xlate next time you have the issue or do a debug nat 2 to see if there is a problem with a port-map translation failure.
An example of an error would be :
nat: ERROR - existing mapped binding for Inside:x.x.x.x/xxx
nat: ERROR - alloc portmap xlate 6 Inside:xxx/xx-> Outside
