We have a NW5.1 with BM3.5 set up as a slave in a Master/Slave VPN
tunnel and it is doing only one tunnel with the other peer which has
also a NW5.1 BM3.5.
On the other hand I recently set up a new VPN server with NW6.5 and
BM3.8 doing several S2S tunnels.

I wonder if it is possible to bring the Master/Slave tunnel to a S2S on
our BM3.8 server and their BM3.5.

Also I am interested in clustering BM3.8 VPN but I only find
documentation for clustering proxy servers. Is it possible to Cluster a
VPN server with BM3.8?

Thanks in advance,
