I have a Net4501 bridging a cable modem and providing NAT
[Bridged Network] ------ (sis2) (sis1) (sis0) ----- Cable Modem (no ip) | (cable modem IP) | | (NATed network, 192.168.0.0/24)
What I'm trying to do is get the computers behind the cable modem to get access to content on the NATed network.
I have a rdr on sis0 which will deflect things from the public IP to a machine behind the NAT
# HTTP to cesium
rdr on sis0 inet proto {tcp} to port 80 -> 192.168.0.23 port 80
rdr on sis0 inet proto {tcp} to port 443 -> 192.168.0.23 port 443
This doesn't seem to make clients on the sis2 side of the network capable of accessing content on that IP though. The IPs the cable modem leases are not at all on the same network (67.174.157.x, 67.174.168.x, etc all with a 255.255.255.0 netmask). The modem seems to do some routing of its own, but this may be complicating the matter.
Is it possible to 'steal' traffic on the sis2 interface and push it into the NATed network?
If so, how?
Thanks for all your help.
