hello , i have some rutx09 on latest firmware and i am encountering an weird problem with 4g connection.
my setup is as following :
4g sim with private APN that has static ip and connects only to my servers in my enterprise network (no internet)
l2tp client on rutx so it can connect on mikrotik CCR in my enterprise network.
then all the trafic of rutx goes through CCR and finaly lan clients can reach enterprise network and internet.
my problem is that i have some network timeouts , and some applications doesnt work properly.
same setup on mikrotik 4g routers work fine , but on teltonika i get timeouts.
no firewall rules are applied. CCR setup is simple and stable , it was working fine for 2 years.
i think i am missing something on teltonika devices , even thought rutx have minimal config.
