SA250 VPN/NAT issue

Unanswered Question
Mar 8th, 2010

Hi,

I am new to the SA520 and have the situation I describe below - any assistance will be greatly appreciated.

I have a SA520 at my site and need to setup a site to site VPN with another company. Two issues: 1. My ISP connection to the SA520 uses PPPoE and so the IP information is auto assigned. I need to use another IP address of out my small public IP address assignment pool as the VPN endpoint address, however, when I enter the PPPoE profile information, the VPN gateway configuration automatically picks up the first IP address assigned by the PPPoE protocol. Is it possible to assign a 2nd IP address to the WAN interface and use that 2nd address as the VPN endpoint?

2nd issue: The SA520 seems to automatically apply NAT exemption to the traffic being sent through the site-to-site VPN tunnel. I need this VPN traffic to be NATed to the SA520 WAN interface since the company to which I am making the connection will not allow  private IP addresses into their network through the tunnel.

Thanks in advance,

Steve

I have this problem too.
