No default route at 3G WAN Link (solved)

Guest · May 12, 2012, 3:21 PM

Hi -

First the good news:
when i use /etc/ppp/ppp.conf with ppp -auto inet_conn, i can perfectly reach outside hosts via tun0.
(with wan Interface deactivated in pfsense)

Now the problem -
when i use pfSense for the ppp dialup, activating the wan link there

i get a ppp0 interface which has a wrong ppp destination address attached.

Did i do something wrong ? I will post screenshots and logs shortly.

What do you mean "- i get a ppp0 interface which has a wrong ppp destination address attached."? That's assigned by the provider when you connect.

Please describe the process by which you came to the conclusion the ppp destination address is "wrong". As cmb pointed out, it is unlikely the ppp destination address is "wrong". In the absence of other information I'm guessing something doesn't work, the ppp destination address is not what you expected and you have latched onto that as the cause.

I don't have enough detail about your configuration to understand the relevance of:

Hi - Thank you for your help -

please check tun0 and tun0.log.

109.84.222.122 is logged as myaddress
10.0.0.2 is logged as hisaddress
with this data, i can reach hosts in the net.

Now for ppp0 - Here i get

109.85.88.51 (not noted as myaddress)
and 10.64.64.0 as a PPP Peer address (which, in my understanding, cant work cause its a network number)
With this data, i cant reach any hosts.

My 3G link gets a PPP peer address of 10.64.64.64 and I don't have any obvious trouble reaching any hosts.

IP addresses on point-to-point links such as PPP typically have network masks of 32 bits so all the address bits are host address bits.

Have you done anything to make the PPP peer the default gateway? I THINK that happens automatically if the PPP interface is the pfSense WAN interface.

Oh, your right - im running under VMware and remember first choosing em0 as the Wan link before i switched to ppp in the widget. I check that … Hey, default was at em0 (which is now lan) and not on ppp - thank you
works like a charme now !
