Hi all,
I am trying to do a NAT translation on R4 so that the packets are sourced from 10.1.1.11.
[r4] -- pix -- [r1]
r4 20.1.24.4 -> 10.1.1.11
So, if I ping to r1 (10.1.1.1) it should see it as sourced from 10.1.1.11 instead of sourced from 20.1.24.4.
R4:
!
interface FastEthernet0/0
ip address 20.x.x.x.x.255.0
ip nat inside
duplex auto
speed auto
!
interface FastEthernet0/1
ip address 20.1.45.4 255.255.255.0
ip nat outside
duplex auto
speed auto
!
ip nat inside source static 20.1.24.4 10.1.1.11
ip http server
no ip http secure-server
ip classless
ip route 10.1.1.0 255.255.255.0 20.1.24.254
!
R4#debug ip packet
IP packet debugging is on
R4#ping 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/8/8 ms

Why don't you Nat the address from the PIX firewall? You can use the Global and NAt statements to do this.

I don't want to do that. I have a static configured on the PIX firewall.
static (inside, outside) 10.1.1.11 20.1.24.4 netmask 255.255.255.255 0 0
I want to configure NAT on R4 so that the the R1 sees as sourced from 10.1.1.11.

may be
interface FastEthernet0/0
ip nat outside
