Actually most firewalls block everything, and mine's one of those. .... Maybe we're used to a different kinda network. A good firewall should block data from escaping your LAN as well as entering it, it's important in case the physical security is breached - bad stuff sometimes comes from inside the building. In fact, a really secure setup will block all traffic even internally, for example to stop a worm from spreading, or to stop users from wasting backplane bandwidth with unwanted traffic. Right you are, I'm using SSH... I tried read-only access just now, and it failed in the same manner. Looks like unsecure SVN is down!
