VPN configuration with Alcatel SpeedTouch 510

How enable VPN through Alcatel SpeedTouch 510? In my case I use VPN server inside with ip address 192.168.1.1, ip address of LAN router is 192.168.1.254. Admin web console is accessed typing

http://192.168.1.254

In NAT configuration add

New protocol TCP Inside IP: 192.168.1.1 Inside Port: 1723 Outside IP: 0.0.0.0 Outside Port: 1723

It was PPTP. L2TP needed

New protocol UDP Inside IP: 192.168.1.1 Inside Port: 1701 Outside IP: 0.0.0.0 Outside Port: 1701

First you should save configuration with Save All and close Admin web console. Now we need configure GRE protocol. Run

telnet 192.168.1.254

and type command

nat create protocol=gre inside_addr=192.168.1.1 outside_addr=0.0.0.0

and save configuration with command

saveall

If you want use L2TP, you should use IPSec, too. And IPSec requires next configuration steps…
