avast secureline VPN + OSX

Zdravo,

Ko se želim povezat na optimalno lokacijo, me vedno znova vrže ven.. povezave nikakor ni mogoče vzpostavit

The VPN server did not respond. Verify the server address and try reconnecting.

Potem sem našla tole na avastu:

If SecureLine VPN is unable to establish a connection, try the following solutions:

Your device:
Some routers have the option to enable or disable IPsec, sometimes displayed as VPN passthrough. For SecureLine VPN to connect and function properly, ensure that IPsec or VPN passthrough is enabled.
Consult your firewall vendor to check that UDP port 500 and UDP port 4500 are open on your firewall.
If SecureLine VPN is still unable to establish a connection, try to uninstall and re-install the software.

Sem na T2 omrežju. Kako nastavim te nastavitve na macu?

Če ga imam vklopljenega ne morem ne na mail, ne na nobeno stran:
