Hello, I have been fighting this issue for some time now, and I am not sure where I am going wrong. We have a PC that with VNC installed. I can get to it without issue internally from port 5900 (VNC, and Telnet). however when I try to access it from outside the firewall It does not connect. To my knowledge I have all the ACL's, NAT and Firewall rules in place to support this, and I do not believe that there is a 'fixup' command for this. Could somebody take a look and see if they can ponit me in the right direction? Thank you!
