How to organize multiple tunnels on Cisco 881?

Question

VPN

Hello IT community! In general, the essence of the question is this: how can I organize several VPN tunnels that are incompatible with each other on a Cisco 881 router?
The task is this: the first tunnel will be on clients, L2TP VPN tunnel; the second one will be on the administrator's endpoint, at the end there is a Mikrotik RB750 router, it was decided to run an IP-IP tunnel with IPSec encryption there. Everything is set up, each of them works alone, as it should, they don’t want to work together.
The router configuration is as follows:

aaa new-model
aaa authentication login default local
aaa authentication ppp default local
aaa authorization exec default local
username ПОЛЬЗОВАТЕЛЬ_L2TP password ПАРОЛЬ_L2TP
vpdn enable
!
vpdn-group L2TP
