Routeros 6.22,bridge ovpn on esxi 5.5?

Question

Computer networks

Good afternoon, comrades, I have router os installed on vmware esxi 5.5, an ovpn server is configured on it and remote objects are attached to it. The ovpn tunnel is combined with an interface on the local network and when connected it dynamically enters this bridge, but pings from the network do not go to the remote object, although the bridges ping each other from Mikrotik, i.e. they see. The iron Mikrotik is configured in the same way and it works without any problems. It’s embarrassing that the bridge in Routeros has the L2mtu 65535 parameter, and on the hardware L2mtu 1598. You can’t change this parameter in any way, it is inactive, although this may not be the case.
