So this is not a good solution technically. So it seems to be a driver problem inside Router OS.Īnyway the ppp connection is really slower than LTE and is CPU hungry. The same modem works under Windows 7 and deliver the WAN address through RNDIS interface. This is a terrible solution.įlashing the E3372h in Stick mode (it become an E3372s modem), an USB port appear inside Router OS, but PPP connection on this port does not work for me (Mikrotik HAP RB951, Router OS 6.38.5). More this flashing is not supported by the modem vendor. But router mode and NAT will stay anyway enabled. The best we could do here, is to flash a modified web GUI in the modem, to give access to port forwarding and DMZ settings. We end with a double NAT setup without possibility to configure any port forwarding. Very bad when we use a Mikrotik for advanced network management. So in the end we get a 192.168.8.0/24 nated subnetwork from this modem.

Router mode is mandatory and DMZ or port forwarding is not available in the modem configuration (through web interface). The USB LTE 4G modem i tried, a E3372h from Huawei, can't deliver the WAN ip address through IP passthrough. To remove that limitation we need bridge mode inside the modem, or IP passthrough. +1 to be able to put an LTE interface inside a bridge.īut this will not remove the biggest problem, the NAT inside the LTE 4G modem. I would get rid of any additional equipment, if Mikrotik would support getting Public IP directly on WAN instead of using old RAS modems and PPP connections. Both HiLinks, and both connect to the Internet immediately when connected directly to laptop. I have tried on 2 different dongles (E3372s and M-150 which is actually E3372 too) and it is the same. 5-6 minutes for dovado to establish connection. The only disadvantage I have encountered is that it takes approx. If the connected device is Mirkotik router, then you have that IP assigned to your ether1 (WAN) port. So, if you connect you laptop by wifi, your IP will be redirected to your wireless connection. As the result you have the IP address from your ISP assigned to the device directly connected to dovado router. Dovado gives the possibility to bridge USB device with LAN/WLAN ports. I am now using dovado tiny router with E3372s dongle in USB. However, I have temporarly fixed that problem.
