i am trying to forward ports range of 10,000 to 20,000 for a customer PBX. normally i would use 1:1 NAT but he is requesting for specific traffic ports.
public int: 192.168.1.3
internal IP: 10.0.1.49
My running config for NAT:
ip nat inside source list 101 interface FastEthernet0/0 overload
access-list 101 permit ip 10.0.1.0 0.0.0.255 any
