Hi All,

I just got a Huawei e1752 3G broadband modem. It to works fine under
Network manager (Opensuse 11.1 x86_64, using usb_modeswitch) and can
connect to the Internet. However, I would like to share the Internet
connection with other computers using a wireless router. I have two NICs
in the computer using the 3G modem. The USB modem doesn't show up in
yast-firewall or in yast-network settings so I am not able to share the
connection through masquerading using firewall/network settings.

Anyone successfully shared this type of connection? Any pointers would
be appreciated. Google has not been my friend so far...

Cheers

Wodans

When it appears to the system as ttyUSB0 as you write in the title,
it probably exists in the networking as PPP0.

Thanks Rob,

You're right, it shows up as PPP0 but I'm still not able to share the
connection. Any pointers?

Cheers

left this residue on the plate:

First, please don't top-post. A lot of people don't like it and won't
reply to those that do so repeatedly.

Look at masquerading. It's been many years sine I did anything like
that. Basically, the one with the broadband router will be the gateway
for the other machines and masquerade the connections for those other
machines behind it. I think it can be done using SuSEfirewall but,
since I preferred to roll my own ipchains and, later on, iptables
rules, I don't know how it would be done that way.
