SSL Not Working from Outside LAN

SSL Not Working from Outside LAN

am 06.10.2002 16:03:13 von Jeff Umstead

I've recently added a Red Hat 7.3 Linux server to our network running Apache and
mod_ssl. My problem is I can't make an https (over standard port 443) connection from
outside our network. I can connect via http (port 80) from both inside and outside our
LAN.

I have the necessary port pass throughs, firewall rules etc in place for both ports. It
works perfectly from inside our lan (subnet) to either http or https but not from our other
sites (different subnets) or from the internet.

I believe the problem is either an incorrect setting in httpd.conf or perhaps in a network
configuration file I've overlooked. Or ???

Any help / tips would be greatly appreciated.

Thanks

How about a simple test to ensure it is not the firewall. Set apache to
listen to HTTPS across port 80, which you already know works outside the
firewall. Then you can easily test to ensure it is not the firewall.

Good idea! I'll have to wait until tomorrow to try that.

I did however do some packet sniffing and noticed that tcp packets
from outside the firewall do get to the web server and the web
server returns tcp packets. But never returns any SSL ( actually
SSLv2 protocol I think) packets. Watching the packets for http the
tcp and http packets pass back and forth.

Have you also ran "ipchains -L" to see what you get? You may well have set
up a firewall that prevents packets coming in.

If you get this: "ipchains: Incompatible with this kernel", then you don't
have a firewall on the server. If you get anything else, it could be
stopping packets coming in.

John,

I think that was it. I had cleared the ipchains list stopped and restarted it. Even though
it said accept all for input, output and forward it was still stopping it. So I stopped
ipchains from running at start up for all levels restarted the Linux box and it now works!

Thanks for the help

Great. "chkconfig ipchains off" should stop it running in all runlevels.
