L2TP client VPN not working after v7 upgrade

Fri Jun 17, 2022 10:08 am

Hello,

since I am not much experienced with Mikrotik, we have quite simple setup for VPN in our small office.

L2TP/PSK server on CCR with RADIUS accounting, CCR has a public IP on Ether1UPC interface so this should not be "NATed L2TP" variant AFAIK.
NAT only setup for other devices, FW only blocking remote SSH/DNS to router, IP pool has range from LAN.
This works on ROS v6 but not v7. Windows client does not connect with error 809.

Could anyone please advise? Thank You!

Relevant settings below:
/ip address
add address=10.0.0.2/24 interface=bridge1 network=10.0.0.0
/interface bridge
add admin-mac=4C:5E:0C:59:69:D1 arp=proxy-arp auto-mac=no name=bridge1 protocol-mode=none
/ip pool
add name=PPTPtest_pool ranges=10.0.0.91-10.0.0.99

/ppp profile
set *0 dns-server=10.0.0.230,10.0.0.236 local-address=10.0.0.2 remote-address=PPTPtest_pool

/interface l2tp-server server
set default-profile=default enabled=yes ipsec-secret=*** use-ipsec=required
/interface pptp-server server
set authentication=pap,chap,mschap1,mschap2
/ip accounting

/ip firewall nat
add action=src-nat chain=srcnat out-interface=ether1UPC src-address=10.0.0.0/24 to-addresses="public IP"
