Hi,
Under group-policy attributes in webvpn you should have option to auto-start particular smart-tunnel or port-forwarding.
bsns-asa5505-19(config)# group-policy TEST attributes
bsns-asa5505-19(config-group-policy)# webvpn
bsns-asa5505-19(config-group-webvpn)# smart-tunnel auto-start ?
config-group-webvpn mode commands/options:
WORD < 65 char List name of programs to use smart tunnel
bsns-asa5505-19(config-group-webvpn)# port-forward auto-start ?
config-group-webvpn mode commands/options:
WORD < 100 char A valid port forward list
Depending of course if you need smart-tunnel or port-forward or which group you have configured ;-)
