The only way that you would be able to use them is a semi-load-balancing formation. What I mean by "semi" is that all traffic that exits one interface will always return to that one. Also, an entire transaction will go over only one of the lines, meaning you will only get the throughput of one line at a time. The only way to "shotgun" (an ISP had to specifically support modem shotgunning in the olden days, BTW), i.e. do aggregate routing, is if you had a separate routed sub-net and ran BGP on the router connected to the two lines (The rest of the internet has to know that you have two lines and both are available to use, concurrently). Needless to say, this can be complicated, and is not considered a "consumer" setup (most providers will require it to be some sort of business type connection like, T and OC connections, which can be on the order of thousands a month, hundreds for a "fractional" T connection). If the the first is acceptable, there are a number of docs like <http://www.samag.com/documents/s=1824/sam0201h/0201h.htm> that would help (I just did a google search for "balance two internet connections linux", first link) and guides that set up a redundant line also should help (it is actually what you are doing, but actively using the "redundant" line also). I hope that addresses what you are asking about. --Tim ______________________________ < I'm definitely not in Omaha! > ------------------------------ \ \ \ \ /\ ( ) .( o ).
