Having a strange issue. We've opened up ssh & PDM on the outside interface to manage the PIX by specific IP addresses.
The PIX will not allow an SSH session until we initiate a PDM session (either internally or externally). Once an attempt is made with PDM, ssh works great. Reload the PIX and the same problem ensues until PDM is attempted again.
At first I thought this might be related to the IOS version 6.2(2) we were running. Upgraded to 6.3(3) and still have the same issue. We've blown the configuration away as well as tried it on several other 501s....Same issue.
