Greetins, I have two Cisco c1841 routers one running the AdvIpServicesK9 12.4(11)T version which has the problem and the other runs the 12.4(24)T5 IOS version, configuration on them is similar. - SSH remote access
- VPDN access
- IPSEC-ISAKMP Site-to-Site tunnel between them and a third router.
Everything works great on the 24T5 one , the 11T router after a couple of days like 4-5, drops all remote access telnet,ssh,vpdn and also the L2L tunnel unexpectedly. Overall configuration is the same (access-lists etc.). Could it be just the IOS version ? Because it only happens on the older version one. It's like after these 4-5 days a buffer overflow happens and it decides to shutdown all remote access and only way of recovery is by manually hitting the On/Off switch and this is repeatable on the same interval. Thanks in advance!
