Troubleshooting a firewall rule

stevenmedeiros

I have an FWSM 4.0(7).

I'm creating firewall policies within Cisco Security Manager.

I created a simple policy that from a couple of hosts  (10.127.154.8 & 9) to communicate to some other hosts that live on a different vlan(10.127.76.31 &32) and made a reciprocal policy for the other direction. The point of these policies is to allow port tcp/50636 in both directions.

I put this rule at the  top of the ruleset to make sure there are no other rules above it that would negate the rule above.

Yes, I also saved it and "Submitted and deployed" this to the appropriate FWSM

However, In the syslog, I see that port tcp/50636 is still being denied. See attached screenshot

I have also confirmed that this policy is in the config of the FWSM itself.

I have confimred that there is nothing on the host blocking (antivirus, windows firewall) this port

I have seen this type of scenario a couple times before in the past, where I create a policy, it doesn't work right away - then it mysteriously works one day.

I'm wondering if there is abug in this software version for this type of activity? Any comments on what I could try to get the policy working?

Thanks!

You might want to check if you have hit the hard limit on the ACL configured on the FWSM.

Is this multiple context or single context mode?
