Subject: Users can't see web server behind firewall
Using ipfwadm to firewall a web server and
masqurade workstations in a small office. PPP to ISP and single ethernet
segment for the LAN. Masqurade works fine but I am not able to forward tcp
requests to my web server which resisdes inside the firewall. Workstations
can see both serves and the internet. Internet users (external) who browse
to the firewall see the default Apache page on the firewall server and not the
pages on the internal web server.
Here are my rc.local entries (Running RedHat
2.0.31)
#This one is supposed to forward tcp to my web
server (not working)
ipfwadm -F -a accept -b -P tcp -S 0.0.0.0/0
1024:65535 -D 192.168.1.2 80
#These entries are for masquerading the
workstations (working)
ipfwadm -a m -S 192.168.1.3/32 -D
0.0.0.0/0
ipfwadm -a m -S
192.168.1.4/32 -D 0.0.0.0/0
ipfwadm -a m -S
192.168.1.5/32 -D 0.0.0.0/0
ipfwadm -a m -S
192.168.1.6/32 -D 0.0.0.0/0
