setting up a GWGuardian server with 2 groupwise systems...

i successfully NAT local groupwise to GWGuardian...

now having trouble with the other Groupwise system
this groupwise system is on different subnet with a different Bordermanager
server
this bordermanager server handles the NAT to the groupwise system...
when i changed the NAT to the GWGuardian server... nothing happens...
no email goes through and the NAT doesn't reponse to pings

this site with the different BM and groupwise is in different city...
and connected by a cisco router

i would like to know if this can work...

thanks
