Hi, I have a cellular modem that configures a ppp interface for IP communication. I would like to bridge the ppp and Ethernet interface together. brctl does not allow for bridging between ppp and ethernet interface. I expect this mainly due to the fact that I am trying to bridge 2 different layer 2 protocols, PPP and Ethernet. I have seen mention that many ADSL routers support "half bridge mode" or "ZIPB" (Zero IP Bridge), this is also called IP-Passthrough. Basically I need a device that works like a modem such that the Public IP address that the modem receives from the ISP is passed trough and assigned to a node (router or SINGLE host). One of the devices I want to connect doesn't play well with NAT nor does it have the ability to support PPPoE/USB Modems. I am also trying to make a secondary modem as a failover connection that uses a 3G modem. A company by the name of cradlepoint sells a device that does this called the CBA250. I have a Linksys NSLU2 that would be PERFECT for this, I just don't know how to do it. If possible I would also like to be able to firewall a little too. http://www.evdoinfo.com/content/view/2601/64/ I want to do this to, just with Linux. What code should I look at to do this or is there a way to configure the system to do what I want. In a perfect world ppp and ethernet would bridge and play nice but its not. Any advice would be greatly appreciated. I am more than willing to write code to get this to work but I'm pretty new to this and have no idea where to even start.
