Hi. this is a strange one. We have a C7200R (FastEthernet) on one side and a C3500 (FastEthernet) on the other with an IPS4240 in the middle. When changing the IPS unit from "bypass-mode on" to auto the interface on the C7200 router goes down, ie no link activity. We have tried several combinations of interface speeds\duplex. The systems would normally be in speed auto\duplex auto but we have tried 100\full forced as well. When in "bypass-mode on" the all systems work fine in auto\auto negotiating 100\full. Any ideas. Thanks Alex
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
