[c-nsp] icmp breaks ipsec tunnel

[James Baker]

Has anyone seen an issue where ICMP on the  external interface or to an
IP address which would go across a IPSec tunnel on a Cisco 877 router
would cause the IPSec tunnel to reset?

 

i.e.: 

 

ping external IP = tunnel drops

ping protected IP = tunnel drops

 

however RDP works fine across the link

 

ICMP is allow both to the router and across the tunnel, I can see the
ICMP hitting the router and a reply being sent

 

This is a 877 running 12.4-15T11 (ADVIPSERVICESK9) running ADSL (PPPoA @
MTU 1492 & MTU 1500)

 

Thanks
