Hi all
I have a router that has only an ISDN connection to the WAN
so i did the usual BRI configuration and configured and DIAL GROUP for the interesting traffic
The issue is that only 1 IP can initiate the ISDN call, and that IP is natted
ip nat inside source static x.x.x.x y.y.y.y
int fa0/0
ip nat inside
int BRI0/0
ip nat outside
My question is, should I configure the access list of the interesting traffic (dialer-list) to match the traffic with IP source before being natted (x.x.x.x) or after being natted (y.y.y.y)
