You're not running BGP, right ? You have a single Linux router that has three physical interfaces : one connects to ISP A, the next to ISP B and the third to the internal network, correct ? Let me know if I got all this right. If so then we run much the same setup here and I can tell you how we configured it (I do remember it took several days of reading kernel source code and tcpdump'ing to get it all working). _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
