I'm setting up a network that looks like this:
--Internet----Router---Firewall
|
| /--- host
Switch----NAT-----<----- host
| \----- host
| \----- etc...
---------
| |
email ns
In other words, a fairly typical small network. I've got an 8-IP
subnet; all hosts outside the NAT have real IPs:
router: 1.2.3.193
firewall: 1.2.3.196 fxp0
1.2.3.197 fxp1
nat: 1.2.3.198
email: 1.2.3.194
ns: 1.2.3.195
The problem I'm having is with my routing. Surprise. Here is
the routing table for the firewall:
default 1.2.3.193 fxp0
1.2.3.193 link#1 fxp0
1.2.3.192/29 link#2 fxp1
1.2.3.196 lo0
1.2.3.197 lo0
The gateway_enable (net.inet.ip.forwarding) is also enabled on
the firewall.
From the firewall, I can reach any host with no problems. However,
from hosts inside the firewall, I cannot reach outside, and vice
versa. I feel I must be missing something obvious, but have played
with routes for hours to no avail.
Does anyone see a problem with the routing of this network?
Greg
