Re: Problem with Huawei E3372 4G modem

Thu Feb 16, 2017 6:34 pm

This is probably a noob question but I am new to Mikrotik routers (even routers in general).

I got my E3372h (Hilink) working with excellent speed by adding a DHCP client and a NAT rule.
(It is however very frustrating that the router DHCP client does not get the public IP address of the
LTE connection. II have found no way around this). I am planning to use the 4G link as failover link
with a script, so not having the right public IP is not great but sufferable.

Now my question: I currently use the factory default firewall rules.
There are two rules that are explicitly mentioning my main WAN interface:

chain=forward action=drop connection-state=new connection-nat-state=!dstnat in-interface=sfp1 log=no
chain=input action=drop in-interface=sfp1 log=no

Shall I add a copy of each but with "in-interface=lte1" or does the NAT inside the modem perform this?

Thanks in advance.

Of course because the LTE stick has a NAT function it also blocks all incoming connections.
However, it never hurts to add another rule like the one that drops input from ether1, but for lte1.
It would be nice when the NAT in the stick could be circumvented (apparently there is a way, but I have
not found how that should work), but remember there is probably another NAT inside the mobile provider
network so this will still not give you a real public IP and untranslated traffic (required for some protocols).

I am using Telia here in Sweden and they have no NAT so incoming connections work fine if you can just get the public IP.

The irony is that the Dovado routers (http://dovado.se/en/) circumvent the IP mode so using the E3372 with those the
router gets the public IP so you can run a server, send SMS, check link status etc. while connected.

Dear Mikrotik, we really-really need this functional :)
Please, implement this.

What problem do you have and want to be solved?
Also, make sure you bark up the correct tree, e.g. when you don't want NAT. The NAT is happening in the Huawei,
so you should ask them to fix that.


We need to get ip address from provider to mikrotik and have full lte-speed.

PPP - not full speed
HiLink - not ip address directly to mikrotik
NCP - solving of problem, but not implemented by Mikrotik yet


ANY reply from Mikrotik to our request?

PPP for Huawei E3372 not only full speed but most important is it crashes every time you try to download more data (higher bandwidth)!

Mikrotik please answer!

Exactly. This is the reason why I had to add dovado as a USB-Ethernet bridge. However, it would be much better to have LTE dongle managed by MikroTik.
