Hi Raju,

from sometime I was able to do telnet on my router or sometimes I can do telnet....Including my user thru RRAS....I can only access perfectly from console.  I tried checking the logs and saw some unusual error.

Craju,

thanks for the support.  I noticed this happens when 1 of my circuit was upgraded.  Recently in my old circuit i'm using tunnel interface with DHCP on my physical interface unlike with my new link i uses my physical interface as the destination point for my VPN.

Workaround:

i am disconnecting my new link then i can do telnet and RRAS.

does this affect the cpu processes of my router from previous and current setup?
