I setup L2TP + ipsec connection between my mikrotik AP to remote Mikrotik controller. Basically I want my latptop wireless connect the AP to get ip address from the remote controller through L2TP tunnel. I configure AP lan as dhcp relay with the wan ip address of controller.
From the mikrotik controller l2tp tunnel, I can find it receives the dhcp request. But it doesn’t process it. Meaning AP sends dhcp request and controller l2tp receives it but controller wan dhcp server doesn’t process it.
To check the issue, I use traceroute tool in winbox of AP, to traceroute the wan ip address of controller. I can traceroute successfully all udp ports except 67/68.
I checked no drop 67/68 ruler in mange firewall.
Anybody has an idea about it? Please help.Thanks.
