Im trying to configure a vpn server on a uc520 and i think i have it done correctly. However, when I try and connect, I get an error almost imediately telling me that im disconnected? Any ideas?
Check if you have firewall that is blocking the Vpn connection. Make sure following ports are opened on UDP port 500 - Which is for ISAKMP , UDP port 4500 - Which is used when the client is coming through a NAT device , ESP protocol - which is protocol 50 used for encryption. Go through the Acceslist statement carefully to allow the ip traffic on Bvi interface. Refer URL
