i have been trying to use port forwarding on an adsl router with ISP assigned public IP address on the dialer0 interface. i also have an ASA 5506-X behind the ADSL Router with a /30 public IP address.
i have the ASA working fine using ip nat inside source 22.214.171.124 126.96.36.199
where 188.8.131.52 is the dialer0 ISP assigned address and 184.108.40.206 is the public IPaddress on the outside interface of the ASA
Now i am trying to get anyconnect working through the router and have configured port forwarding as below:-
ip nat inside source static udp 220.127.116.11 4500 18.104.22.168 4500
ip nat inside source static udp 22.214.171.124 500 126.96.36.199 500
ip nat inside source static udp 188.8.131.52 443 184.108.40.206 443
ip nat inside source static tcp 220.127.116.11 443 18.104.22.168 443
i have also used the keyword "extendable" after the port forwading line , but no joy
when i browse to https://22.214.171.124 i cannot get to the ASA , i have also tried using the pre-download installation of anyconnect and that just times out when i connect to 126.96.36.199
i wanted to know if we can port forward from one public IP to another public IP ? i created the anyconnect using the ASA wizard.
i suspect the router is the cause of this for now,
how do i convert the cisco 887 VA router to a bridge mode - this is my last resort , ideally i dont want to do this as its a major outage on the network
can the ASA have a 192.168.1.1 outside interface address and use port forwading for anyconnect to work.
any assistance will be great.
i have attached a copy of the config
Can you browse to https://188.8.131.52 from the outside? Note you can noy use AnyConnect from inside the ASA.
Are you sure AnyConnect is enabled? Have you go something like:
