Hi,
my router has assigned static public ipv4. Firewall makes masquerade. In filter there isn’t any entries, in nat(only one, for masquerade) also. Upnp is enabled.
And I have got problem with ipsec client on computers behind nat. They can’t connect. When I use cheap Tp-Link router for 15USD all works.
How to configure to passthrough IPsex/L2TP traffic?
