DHCP problems with 3G modem in combination with PPP

jozef00

Hi,

I am trying to get a 3G modem working with pfsense. What I want is that pfsense secure internet provides in the field over a 3G modem from XS4ALL.
The systemlogs gave the following over this device:

"kernel: ucom0: <huawei 0="" 2="" technology="" huawei="" mobile,="" class="" 0,="" rev="" 2.00="" 0.00,="" addr=""> on uhub4".</huawei>

There are no PPP errors, so the modem is talking with pfsense. But when I run the ifconfig command, I see that tun0 got a IP in the 10.0.0.0 range. So he got no IP from XS4ALL, because when I connect the modem with a Windows PC he obtains a 83...* IP (I am forgotten the right IP). Here you got my ppp.conf:

#####################################################

 ident user-ppp VERSION (built COMPILATIONDATE)

 # Ensure that "device" references the correct serial port

 #
 set device /dev/cuad1

 set speed 115200
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
           \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
 set timeout 180                        # 3 minute idle timer (the default)
 enable dns                             # request DNS info (for resolv.conf)
# enable dhcp

 # the values which have been assigned by your ISP.
 #

 set phone *99#
 set authname internet
 set authkey 1234

 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
 set dns 208.67.220.220 208.67.222.222  # openDNS
 add default HISADDR                    # Add a (sticky) default route

I think that forcing the modem to obtain a IP by DHCP is the solution. But I can't get it configured in pfsense.
When someone need more info I will post it on the forum.
If someone could help it would be great!

Kind regards,

Are you trying this on pfSense 1.2.3 or 2.0?

There is built-in support for 3G modems in pfSense 2.0

Hi jimp,

Thanks for your reply!
I am trying v1.2.3 and that is because it is the latest stable version. Or do you think that the current 2.0 beta is stable enough to use in a production environment?

Kind regards,

You're not going to get that functioning on 1.2.3 without a lot of manual hacking. Use 2.0.

Thanks guys, I will try the 2.0 beta.

Kind regards,
