L2TP/IPsec dropped after site-to-site IPsec configured

RouterOS General
1

Hi!
I have to Mikrotik routers (2011UAS with RouterOS 6.11 and 951G-2HnD with RouterOS 5.26). Before the second router appeared I had a L2TP/IPsec configured and could log in to my network from mobile phones. After the second router appeared, I configured a site-to-site
IPsec connection between the two and it worked too, so I have a common network on my two sites (10.161.0.0/8 and 10.161.8.0/21).

However, after a site-to-site IPsec started working the previous L2TP/IPsec to the first router stopped working. I can no longer remotely connect from my mobiles.

Can anyone help? I attach a log where there is an attempt from a mobile (85.26.183.149) to connect to the first router (46.41.67.192). The third IP 77.66.234.235 is my second router. It seems that the attempt from a mobile just dies out for some reason.

Hello,

do you using SPI&NAT on both routers?

We can look into our crystal ball when it returns from the shop. In the meantime, you could post your

/ip ipsec export
