IPsec tunnel fails with NAT device plugged before MT router...

Howdy. I’m still struggling with firinng up 2 vpn tunnels (2 mikrotiks → draytek vigor v2860).
Everything seems to work fine on my test enviroment, where I can put both MT’s with public static IP addresses on WAN interface ports. But whenever I try to place a 3rd party router in front of MT (in this case MT has no longer public ISP WAN IP just some local one like 192.168.xx.xx recieved from additional routers LAN side)
Obviously I’ve tried setting up DMZ feature on router pointing Mikrotik but doesn’t solve the issue.
Trouble is I see some communication attempts on MT ipsec logs but it usually fails with phase2 errors like:

09:33:27 ipsec,error 83.9.xxx.xxx failed to pre-process ph2 packet
...
...
09:33:30 ipsec,error 83.9.xxx.xxx peer sent packet for dead phase2

83.9.xxx.xxx is Draytek’s WAN IP.
192.168.73.37 - MT’s WAN IP (with additonal router attached)
192.168.73.1 - additional router IP
I’m using 3DES MD5 encryption protocols as suggested on Draytek’s manuals for Mikrotik VPN tunnels. As said before - tunnels gets established quite fast and stable with MT set directly with public WAN IP (tested on DSL modem). Almost forgot. Draytek is set in Dial-Out tunnel mode, since both MT have/will have static IP. Draytek obtains dynamic public IP once in a while. Also Draytek has no other device above - it’s connected to phone line directly (vDSL modem built in). It has also secondary WAN with static IP but slow speed. Using other secondary WAN changes nothing.

Now I’ve read that MTs have issues using L2TP IPsec behind NAT, but isn’t there any workaround for that?

Hi jaceqp123,
please post your ipsec P2 configuration.
result of

/ip ipsec policy print

this P2 policy need to have folowing config if you have router behind your mikrotik, and correct port forwarded of course.
SA Src address you wanrouter facing ip. (192.168.73.37)
SA Dst address remote side wan public ip.

It seems to work for a longer period of time now. My current ipsec policy of one of my MT’s shown above.
BTW. Had some issues with renewing VPN tunnel using static ipsec policy only (shown as no.1). It still remains active, though as can see I’m using ‘generate policy’ atm. Also I’m using a script checking dyndns current IP of VPN server (Draytek), but the script is working correctly.
