i am facing one issue ,
i am having site to site vpn beween dynamic to static ip between two sites .
dynamic is a ADSL line.
the vpn is working fine but my problem is every day one guy has to intiate from dynamic to static side then only the whole day it is working ,like if ideal for few hours the vpn is dissconecting .
so there is any solution to keep this connection permeantly
i tried "lifetime to none and 86400".
