You've declared zvi.t-networking.com (206.117.19.2) as your gateway, but your FreeBSD box is ivz.t-networking.com (206.117.19.10). zvi.t-networking.com appears to be the other end of the ppp link, so arp can't find it. Change your gateway address, and you should get further. If tun0 still doesn't do anything after that, make sure that ivz has its default routing set correctly. You'll also need to tell zvi that zzyx is at the other end of the link. I note you have another problem: zzyx.t-networking.com isn't known outside your local net. Have you finished your DNS setup yet?
