Hi i'm working on a OpenBSD firewall; connecting a lan to the Internet through two adsl's. I connect each one of the adls's to one ethernet (txp0,txp1) on the OpenBSD firewall, everything works great, but i found strange that on the arp table of the firewall i have the same mac address for both adsl modems. I run: # arp -an and i get: ? (modem1.ip) at 00:04:4e:79:cc:38 on txp0 ? (modem2.ip) at 00:04:4e:79:cc:38 on txp1
I get to this when I need to add more adsl modems to the same firewall, but didn't have more ethernet interfaces. I tried to configure three ip addresses in txp0; connect txp0 to a switch and the three adsl's to the switch, but didn't work. Is there a way to get a pool of adsl's connected to only one ethernet interface? I presume that the problem came from getting the same mac address for all the adsl modem's used. Thanks for any suggestion Mario
