Hello,
We are using 1to1 NAT in Opnsense v23.7.
1 Public IP for WAN Interface, 2 Public IP addresses as Virtual IP.
The internal IP address can't access the port via its WAN IP address. So I enabled NAT Reflection for 1to1 in Firewall Settings. Everything worked fine. But after restarting pc, Windows can't ping its own gateway IP address. It gives "General failure". But it can ping other IP addresses on the network and also 8.8.8.8, but DNS also doesn't work.
In Linux machines, there is not such a problem. Does someone encounter this problem? I would be happy to have a solution, because it is very urgent. Thanks.
If there's a problem with Windows but not with Linux you might wanna check your windows for personal firewalls or other "security" stuff first.
I have disabled Windows Firewall. We are using ESET Antivirus without Firewall, just in case I have also disabled ESET Protection, but it didn't help.
