Ok, let's get our hands dirty :)

Site A - NG AI R54. Has frame-relay link to SiteB and link to internet.
Site B - NG AI R54. Has Frame-relay link to SiteA and link to internet.
Site C - NG AI R54. Has internet link Only.
Smart - SmartCenter managing all 3 firewalls.

SiteA ------- SiteB connected via frame relay link.
SiteB ------- SiteC Connected Via VPN tunnel over the internet

Now I want to set up a VPN between SiteA and SiteC. However, in the general properties 
of SiteA firewall, the IP address is that of the frame-relay link and not the external 
IP address of the internet. Therefore, I was facing a problem initiating a VPN tunnel 
between SiteA and C. I even tried the dynamic resolution option but to no avail. 
Therefore, I finally gave in and decided to change the IP address of  SiteA in the 
General properties to that of the external. It went well. I changed the IP, reset the 
SIC and restarted the module for safe measures.

Before this change, all communication between Site A and B was fine, all over the 
frame-relay link, in the clear. As soon as I made the change, all traffic from SiteA 
to SiteB was being dropped. The reason being that SiteB logs the error as "Encryption 
error:traffic sent in clear within an encryption connection.". SiteB obviously sends 
the traffic in the clear, but siteA expects it to be encrypted?!? The rules are still 
the same, SiteA SiteB ANY ANY ACCEPT and nothing in the VIA column, just ANY. THere is 
NO VPN community between SiteA and B. I even removed ALL Vpn communities and left only 
SiteA---siteC VPN community... still, no use. It only works when SiteA itself is NOT 
part of ANY community (star, mesh).

This email is getting too long. In short, I tried lots of things (and Encrypt all 
traffic is not encrypted) but nothing worked. I ended up with SITEA in NO VPN 
community... but i need it to be. So your help would be much appreciated.

Regards,
Girard Moussa
