I need some help with setting up port forwarding on NetBSD 1.5.2 with generic
My ipf.conf is as follows:
pass in from any to any
pass out from any to any
My ipnat is as follows:
map ne0 192.168.0.0/24 -> 0/32 proxy port ftp ftp/tcp
map ne0 192.168.0.0/24 -> 0/32 portmap tcp/udp 40000:60000
map ne0 192.168.0.0/24 -> 0/32
rdr ne0 0/0 port 80 -> 192.168.0.4 port 80 tcp
ne0 is the external interface that is connected to a cable modem (dynamic IP).
when I portscan my router from work, I see that it has port 80 filtered as I
expect. From my internal network I can connect to the http server on
192.168.0.4. However my connection times out whenever I connect from
outside. I have net.inet.ip.forwarding=1 in sysctl.conf.
I'm out of ideas. What's wrong?
ps: I've also tried rdr IP/32 port 80 -> 192.168.0.4 port 80 tcp, where IP is
my external IP. Doesn't work either.
