#1 apply captures on the other end and see if you get any packet
you should see packets on port udp 500 from the peer
if you do not see it, then contact your isp and get the ports required for vpn opened - udp 500, ip 50,51 , udp 4500
#2 also you will need to open these ports on firewall using access-list on your outside interface
alternativly to open vpn related ports on your firewall you can give the command
sysopt connection permit-vpn

how to do capture for outside interafce ..
08-11-2010 11:45 AM
access-list capout extended permit ip host
access-list capout extended permit ip host
capture capo interface outside access-list capout
i think it could well be the isp blocking it
do you have any other active tunnels on site b
08-11-2010 12:10 PM
yes i have active tunnel connection to other location at site B ,
similarly i have done capture command for outside interface i dont see any traffic for 500 which recieving to my firerwall or my firewall is sending out , similarly i have binded capture acl to inbound direction of outside interface .
similalry by using my ISP connection i can use vpn dialer to connect to my HO ..
