We're using a 2811 router with a static DSL address provided by AT&T. At some point during the day, access to cisco.com PEC and most other (but not all) HTTPS sites was blocked. No changes were made to the router, we've checked ACL's (in fact, we are now allowing all traffic to and from 443), in doing a traceroute to wamu.com, for example, it reaches about 12 hops then fails. Any ideas ?
I have this problem too.
