hello, all this is my topology:
R7, R8, and R9 are virtual machines inside the network
and they have a default route to the switch and the switch has a default route to the Router.
this Is the routers config:
!
hostname Router
!
interface Loopback1
no shutdown
ip address 11.1.1.1 255.255.255.255
!
interface Loopback2
no shutdown
ip address 22.2.2.2 255.255.255.255
!
interface GigabitEthernet1
no shutdown
ip address 10.1.1.2 255.255.255.252
ip nat inside
!
interface GigabitEthernet2
no shutdown
ip address 1.1.1.2 255.255.255.252
ip nat outside
!
ip route 0.0.0.0 0.0.0.0 1.1.1.1
ip route 10.1.2.0 255.255.255.0 10.1.1.1
!
ip access-list standard NAT
permit 10.1.0.0 0.0.255.255
!
ip nat inside source static tcp 10.1.2.7 23 11.1.1.1 233 extendable
ip nat inside source static tcp 10.1.2.8 23 22.2.2.2 233 extendable
ip nat inside source list NAT interface GigabitEthernet2 overload
!
this is it.
now when I access R7 from the internet with the 11.1.1.1 address it works ok and if access R8 from the internet with the 22.2.2.2 address it works fine as well.
but when I want to access R8 from R7 with 22.2.2.2 address it doesn't work and vice versa.
so I want to fix this issue i and I have looked into different solutions but none has worked so far like NVI with it is not supported on IOS-XE or Hairpin Nat witch also doesn't work.
I need your help.
