All contacts of my list in the Hamachi is with a blue ball. I am running it under a firewall. I need of a specific solution to it. I ever search in all topics and don't resolve this. Please, could someone give me some specific instructions? Thanks very much!
I had the same issue and fixed it by enabling static ports in the NAT firewall of pfsense. See below link for more details on how:
Be careful and test out static ports before going into production (I'm assuming this is a work router and not just a home one) as I've read it will break other functionality such as VNC.
Thanks much for pointing out the solution! The pfSense wiki article is very clear and direct. Note that if you have more than one network set up (for example, a wireless card or additional net on OPT1), you'll need to decide if you need to enable Static-ports on their outbound traffic as well.
here the PF info:
Firewall/NAT/Outbound >> Outbound NAT Mode
Note: can't use destination of Ham IP 220.127.116.11/8 as the connection is doen WAN to WAN address (not with the Ham IP)
