Good evening,
I have the following network configuration:
The local network contains several machines including an HTTP (mimir) server accessible from the Internet. Since I have only one public address, I realize a PAT for:
- clients can access the Internet and ports
- http and https ports (80 and 443) are translated to the address of my server http (mimir).
This gives the following configuration:
interface ATM0 no ip address no atm ilmi-keepalive bridge-group 1 pvc 8/36 encapsulation aal5snap ! ! interface FastEthernet0 description Vers switch principal no cdp enable ! interface Vlan1 ip address dhcp hostname bisfrost ip nat inside ip virtual-reassembly in ! interface BVI1 ip address dhcp ip nat outside ip virtual-reassembly in ipv6 address autoconfig ! no ip forward-protocol nd no ip http server no ip http secure-server ! ! ip nat inside source list reseau-domestique interface BVI1 overload ip nat inside source static tcp 192.168.0.20 80 interface BVI1 80 ip nat inside source static tcp 192.168.0.20 443 interface BVI1 443 ! ip access-list standard reseau-domestique permit 192.168.0.0 0.0.255.255
Unfortunately, translation to the server does not occur when the source is an internal host (eg. A1). To solve this problem, I have set up a lying DNS server that is used by internal hosts through DHCP. Problem, android phones do not respect the DHCP option, use Google DNS server (8.8.8.8) and so, continue to use the public address.
Can you help me configure my NAT/PAT so that my internal clients can access the http server by its public address?
NB: What was tried, without success (I used only one internal interface)
