routing problens

I have 8.0-PRERELEASE updated from stable-supfile. There is a route to the 194.85.80.0/22 subnet, but I can't ping 194.85.80.27.

But if I add a route to the host 194.85.80.27, everything works fine. What should I do to access all computers from the subnet?
If it matters, I have gateway_enable="YES" and IPFW enabled with the only rule "allow ip from any to any"
 
You pasted the routing table when things don't work, but can you also paste the routing table when they do work?

Traces to 194.85.80.27 from other machines (10.55.114.0/23 subnet) go through 10.55.114.1
 
Strange. Without the 194.85.80.27 host entry, what do you get with this command:

Code:
route -n get 194.85.80.27

And what does tcpdump show if you try ping 194.85.80.27 without the host entry?
 
Code:
# route -n get 194.85.80.27
   route to: 194.85.80.27
destination: 194.85.80.0
       mask: 255.255.252.0
    gateway: 10.55.114.1
  interface: rl0
      flags: <UP,GATEWAY,DONE,STATIC>
 recvpipe  sendpipe  ssthresh  rtt,msec    mtu        weight    expire

After adding a route to the host it says:
Code:
# route -n get 194.85.80.27
   route to: 194.85.80.27
destination: 194.85.80.27
    gateway: 10.55.114.1
  interface: rl0
      flags: <UP,GATEWAY,HOST,DONE,STATIC>
 recvpipe  sendpipe  ssthresh  rtt,msec    mtu        weight    expire
       0         0         0         0      1500         1         0

tcpdump shows nothing.
 
Oh, sorry. It was tcpdump on re0 by default.

tcpdump on rl0:

tcpdump on lo0 shows nothing.
 
Your routing table is a mess. A lot of conflicting routes.

Code:
10.0.0.0/8         10.55.114.1        UGS         0        0    rl0
10.55.114.0/23     link#2             U           2       58    rl0
10.55.115.80       link#2             UHS         0        0    lo0
10.55.114.0/23 includes 10.55.115.80 on lo0. 10.0.0.0/8 includes both the addresses on lo0 and rl0.

Code:
192.168.0.0/16     10.55.114.1        UGS         0        0    rl0
192.168.1.0/24     link#1             U           0        0    re0
192.168.1.1        link#1             UHS         0        0    lo0
192.168.0.0/16 includes the 192.168.1.0/24 on re0 and 192.168.1.1 on lo0.

I would suggest cleaning it up and since all routes point to 10.55.114.1 set that as your default gateway.

But I still can't ping 194.85.80.27 and others. Now, I can ping only computers from the 10.55.114.0/23 subnet.
 
I want to use mpd in future. So, in this case I will change the default gateway to the mpd's one and lose access to the local network.
 
We'll cross that bridge when the time comes ;)

For now just see if it works.
 
Ok.. Now slowly start adding the routes, start with that 194.85.80.0/22 one. Add a route, test it and if it works add another until it doesn't work anymore.
 
Thanks. I have found the reason: it was a line
Code:
ifconfig_rl0="inet 10.55.115.80 10.55.114.1 netmask 255.255.254.0"
in rc.conf
