PIX site-site VPN thru Alcatel speed touch ADSL?

[kev_jacob]

Hi,

I have a scenario as such:

I need to establish a site to site IPSEC VPN with another branch. Both the branches have static IP's on Alcatel speed touch ADSL router and private ip's on the PIX firewall's outside interface which is placed behine the ADSL router.

Is it still possible to configure IPSEC Site-site VPN configuration on the PIX with the peer address of the Alcatel ADSl router at the other end. I mean is this possible if I do a NAT from the Alcatel router to the PIX outside private ip 10.0.0.x. Will the IPSEC traffic reach the PIX on both ends.

If not, what do you think is the best way to make this VPN happen between the PIX's.

Regards

Kevin

Yes its possible...

On your ADSL router you need set up port forwarding (from ADSL router to PIX)

You need forward following:

protocol AH (protocol number 51)

protocol ESP (protocol number 50)

UDP port 500

UDO port 4500
