Connect Ub433 to 3g

Hi everyone

I have a Routerboard 433 series, and want to use my 3g usb modem(Huawei E173) to connect to the internet and share this connection over the wireless interface installed on my routerboard. I understand that I have to create a ppp connection to connect the 3g modem to the internet and then use the masquerade NAT function to link the two interfaces(if I understand everything I have read).

The problem is from everything I have read I cannot figure out how to do this. Could anyone help me simply connect the 3g modem to the internet and then share it over wireless?

Thanks in advance!

from winbox > PPP > interface > ppp client add a new interface ppp client

if you have APN or PIN insert that and select your 3g modem from Port Field .

in PPP tab of ppp client entere your username and password and remote address and then ok .

after your connection is established , you need to set ip address to your interfaces and then nat that .

for example :

int ether1 : ip add add address=192.168.1.1/24 int=ether1

for your client need to add Nat rule ( masq ) can be useful for you :

ip firewall nat add chain=srcnat src-address=192.168.1.0/24 action=masquerade

Hi

Thank you so much! It works.

I connect my laptop to the routerboard and I have internet(skype and everything connects), but it is extremely slow, sometimes a page does not load and I have to reload it two or three times before it works. What could this be?
