I've got a Fedora server running Subversion and svnserve on port 3690. My repo is at /var/svn/project_name. I have my router forwarding port 3690 to the local server (as well as port 80, 21, 22 and a few others). When I connect locally to svn://192.168.0.2/project_name it works great. When I connect from an external server to svn://my.static.ip/project_name I get a time out connecting to the host. However, if I http://my.static.ip there is no problem, so port forwarding is working (at least for port 80).

I don't want to run WebDAV or svn via HTTP/s. I'd like it to work using svnserve, as documented in the svn book. What have I misconfigured?

EDIT Here is the last part of my iptables dump. I'm not an expert, but it looks OK to me:

ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:svn
ACCEPT     udp  --  anywhere             anywhere            state NEW udp dpt:svn
ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpts:6680:6699

REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited

EDIT 2 Results from sudo netstat -tulpn
