What are the PSTN cards for? Local handsets? Because in the scenario below you need at least one PCI slot for ADSL cards. Yawarra makes a 1U enclosure that with a PCI riser card will take 2 PCI cards, I believe. Be careful not to exceed your power budget, though. > We currently have separate machines which run our VPNs (and firewalls, DHCP, > and web proxies) on separate ADSL lines, but these machines are > licence-encumbered (in a manner of speaking).

Traverse Technologies makes the Solos PCI card, which comes in 2 and 4 port versions. You can then use multilink to bond several PPP circuits together into a single IP interface, which Astlinux will support. > Is it possible to enable a second external interface in 0.7.2 - I seem to > remember EXT2IF being mentioned in the past - using NIC1 for VoIP and NIC 2 > for everything else, especially VPN and client PC internet access? I'm not sure anyone has ever tried this, and I suspect it won't work... that said, we might be able to fix it so it does work. Not sure AIF or traffic shaping will work correctly over multiple egress interfaces. You might need some iptables trickery to get the correct traffic to flow out over the correct interface. > If this were possible, how would the net5501-70s be likely to perform under > this load?
