Question:
I have a 2811
router that WS-C3750X-48PF-S Price I need to confirm NAT configurations as expected. I have 2 deviced
on the internal LAN that need to access remote resources without PAT. All the
other devices are for a guest network with PAT. My interface Fa0/0 is connected
to local network (1.1.1 .1/23).
Fa0/1 is connected to ISP (10.10.10.178/30). Addressable range from ISP of
10.10.10.192/28 (10.10.10.193-10.10.10.206). Internal machine 1.1.1.2 &
1.1.1.3 must connect to a remote server through internet on spacific port
numbers. Attached is the configuration I have.
Answer:
It would be
easier if you just configure static NAT.
ip nat inside
source static 1.1.1 .2 10.10.10.193
ip nat inside
source static 1.1.1 .3 10.10.10.194
no ip nat pool
static1 10.10.10 .193 10.10.10.194
prefix-length 28
no ip nat
inside source list 2 pool static1
no ip nat
inside source list 3 pool static1
Local devices 1.1.1 .2
and 1.1.1.3 wil be visible from internet as 10.10.10.193, 10.10.10.194 WS-C3750X-48PF-L respectively.
