here is the EXACT arp statement as it is on the existing router, this is what i need to put into pfsense to replace that existing router.
–--------------------------------
IP Address/Bitmask
A.A.A.A/32
On Interface
LAN
Proxy on Interface
WAN
B.B.B.B
On the existing router there is no mention whatsoever of either A.A.A.A or B.B.B.B in the NAT area. I hope this helps clear things up, and thank you so much for your help so far.
