Problem VPN / IPSEC

As far as I remember Win L2TP needs rekeying after a fixed period AND a fixed amount of data (in KB). Search the forums for the exact settings, this has been solved before.

friend Have other topics searched the forum and did not think that will help answer. Below is your settings, follow the entire procedure in the manual: config user group edit " VPN-L2TP" set member " vpn" next end config firewall address edit " L2TP-CLIENT" set subnet 192.168.50.0 255.255.255.0 next end config vpn l2tp set eip 192.168.50.20 set sip 192.168.50.10 set status enable set usrgrp " VPN-L2TP" end config vpn ipsec phase1 edit " L2TP-P1" set type dynamic set interface " port1" set dhgrp 2 set proposal aes256-md5 3des-sha1 aes192-sha1 set psksecret ENC passorwd next end config vpn ipsec phase2 edit " L2TP-P2" set encapsulation transport-mode set keylife-type both set pfs disable set phase1name " L2TP-P1" set proposal aes256-md5 3des-sha1 aes192-sha1 set keylifekbs 250000 set keylifeseconds 3600 next end

I cannot search for you now, but for me it looks highly suspicious that Windows will support AES256. And yes, the values for keylifebs and keylifeseconds need to be exactly the ones that Windows uses.

hello I changed the port to another link, apparently has been resolved, now I have difficulties when trying to register the VPN client, the following debug error: find_tunnel_call () -183: can not find tunnel 1049 handle_network_packet () -197: L2TP: Tunnel 1049 is invalid incoming packet (call = 1050).

VPN connects, but drops after a few minutes.
