Wide Area Bonjour

I'm having trouble getting this to work. I've enabled it in server admin as described in http://docs.info.apple.com/article.html?path=ServerAdmin/10.5/en/c3ns34.html Our office network has a private network of 10.x.x.x/24, and VPN clients connect to the same network and gets addresses in the same range. VPN clients also use our internal DNS server which has wide area bonjour enabled with bonjour.mycompany.com. I can see it's enabled in the zonefile /var/named/zones/db.mycompany.com.apple like this: lb._dns-sd._udp IN PTR bonjour.mycompany.com. I can access the VPN clients from the office and vice versa, it's just bonjour browsing that won't work. All clients use the same internal DNS server. No firewalling.
