NAT Rule Causing Internet Connectivity Issues

[TedEdward]

Hi,

I have a NAT rule on our FPR-1010 running ASA to allow incoming traffic on outside interface on port 65020. The rule works and have required access  externally. 

The problem I have is the internal server that it is accessing has internet connectivity issues. 

For example when I open Chrome on it I can't get to https://www.grc.com but can get to other sites. This is causing problems for the software running on the server.

This is the NAT rule.

(Inside) to (Outside) source static SERVER interface service any 65020Source inactive.

Does anyone know what the issue could be please?

Thanks

(Inside) to (Outside) source static SERVER interface service any 65020 
the source Port is OK 
the destination Port is Wrong ...
service any 65020 at the end of NAT is wrong, this for destination port, i.e.
costumer in outside will ask specific port that NAT to 65020, here you make all destination port NAT to 65020...!!!
please change it to be 
Inside-FW-Outside 
the client in outside will use port for example 5000 will nat to 65020 which use by Server in Inside. 
the client in outside will use port 65020 will nat to 65020 which use by server in inside. 

I think you misunderstood the Service and assign ANY as it the source port.
