Group,
I have run into another NAT problem. This time, what I'm trying to achieve is
that I have 3 servers with mirrored content, & I want to create a "virtual
server" with an IP of 100.20.1.1
ServerA (192.168.1.2/24)
\
ServerB (192.168.1.3/24)- RTA ---- RTB (207.35.14.81 /30)
/
ServerC (192.168.1.4/24)
But when I tried to ping the Virtual IP from RTB, no NAT translation is taking
place, and hence the ping is unsucessful.
here's RTA config...
interface FastEthernet0/0
description Inside NAT - to the 3 servers
ip address 192.168.1.1 255.255.255.0
ip nat inside
no ip route-cache
no ip mroute-cache
duplex auto
speed auto
!
interface Serial0/0
description to Outside - to RTB
ip address 207.35.14.82 255.255.255.252
ip nat outside
no ip route-cache
no ip mroute-cache
clockrate 64000
ip nat pool PoolOne 192.168.1.2 192.168.1.4 prefix-length 24 type rotary
ip nat inside destination list 5 pool PoolOne
access-list 5 permit 100.20.1.1
****** I can ping fine to the Internal local IPs of the 3 servers *****
RTB#ping 192.168.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/33/36 ms
RTB#ping 192.168.1.3

Any help will be greatly appreciated.
