[Bridge] bridge with ppp0

[Bridge] bridge with ppp0

[armin langhofer]

hi there

i found your project and tried to bridge two ppp devices.


you say (http://bridge.sourceforge.net/faq.html) that this is possible:

... "Linux bridging is very flexible; the LAN's can be either 
traditional Ethernet device's, or pseudo-devices such as PPP, VPN's or 
VLAN's. The only restrictions are that the devices:" ...


i tried this but got "br_add_interface: Invalid argument" when adding a 
ppp device to the bridge. adding an ethernet device works perfectly!

00:07:21 protector ~ # brctl addbr br0
00:07:22 protector ~ # brctl addif br0 eth2
00:07:30 protector ~ # brctl addif br0 ppp0
br_add_interface: Invalid argument



the ppp's are done with pppd and pptpd (poptop)
00:09:39 protector ~ # pppd --version
pppd version 2.4.2
00:09:44 protector ~ # pptpd --version
PoPToP v1.1.4-b4


any ideas?

best regards, armin.

You should use interfaces with same MTU size. In same situaion I made 
OpenVPN tunel over ppp conntction with MTU 1500 (same as in ethernet 
network)
