Hello Friends, I would like you to give me some advice, I have an internet connection to my router and I need in the firewall to allow only the ports for l2tp / ipsec, the rule was made saying that it denies everything other than UDP ports 1701 , 500,4500 on WAN1 and to block anything other than 50 (ipsec-esp):! 50 (ipsec-esp).
The intention is that the WAN1 remains to receive the l2tp / ipsec VPNs and that it does not let anything else pass through that interface.
Unfortunately it doesn’t work for me if I make those rules they don’t raise the VPNs, can you give me any opinion? , I thank you very much
are these accept rules above all others?
Post your config.
