NAT Issue

[zulqurnain]

hi all,

if i have setup my router 1800 series for doing NAT, and the router is doing it without an problem except that how do i make that router does not NAT only one specific IP meaning 1.2.3.4 should not get NAT when it reach the outside interface like. i hope i cleared my point.

HI

if u dnot want this IP to communicate with anyone outside then u can apply a inbound access-list on u r ethernet interface.

access-list 10 deny 1.2.3.4 0.0.0.0

access-list 10 permit any

Thanks

Dear,

The router can be configured to stop NAT one IP or even subnet while this subnet still can communicat internal with directly connected subnet.

IP NAT inside source list 10 interface s2/0 overload

access-list 10 deny 1.2.3.4 0.0.0.0

access-list 10 permit 1.2.3.0 0.0.0.255
