Have a cisco 2821running 12.4 (Cisco IOS Software, 2800 Software (C2800NM-ADVSECURITYK9-M), Version 12.4(3g), RELEASE SOFTWARE (fc2) ) that stops responding to client vpn connection initiations after 5-6 weeks of run time. This unit terminates several site to site ipsec tunnels, and also has the 1 ipsec client vpn connection configured as well.
I've read a few cisco release notes that indicate running a 'clear tcp tcb *' might fix this, instead of having to reload. Is there a newer s/w release we should install? Or a fix for this issue?
