Title: IPSEC VPN and Port 80
Post by: Sterling on October 28, 2002, 10:37:22 PM

I have successfully set up 2 SME 5.5 servers with an IPSEC VPN tunnel between the two to connect the networks at our two locations. All is well and seamless until I try to connect to port 80 via http to one of the servers behind the SME 5.5 server remotely. If I change it all to use to port 81 everything works ok. I don't even know where to start on this one. Any ideas?

Thanks,
Sterling

Can you supply more info on how you are trying to connect to port 80.

And could you please explain how do you changed SME 5.5 to respond by another port than default (80) ?

I´m using a ISP that blocks port 80 and my router is unable to route 82  to 80.

Thanks!

Here you have the HOW-TO that explains how to change Apache's Listening port on SME.
http://www.familybrown.org/howtos/listen-port-howto.html

BTW, Sterling, could you explain to me (or show me a HOW-TO) about how to set up SME to work as a LAN-to-LAN VPN Router???
I'm trying to find a solution for connecting several networks (ones running W2000 Server, and others running SME as Firewall) on a mesh topology.
I heard that SME does not allow incoming pptp connections for inside hosts.
Thanks!

I already had been there and even asked for help for his writer. But this is for SME 512 and I´m looking for help on SME 55. Even Mr Brown don´t know was to do this.

Thanks!

Mmmm....I made it work, but on SME 5.12..
As a matter of fact, I rolled back my upgrade from 5.5 to 5.12 since I had a lot of problems with pop-before-smtp and other things like this.

Yeah! I know. Just a few guys fix what isn´t broken, so SME 5.5 just on new installs... and there is so many reasons to do not install SME 55...
But I like to have a new version... by now I found a workaround to my problem.
Using DNS I was able to redirect all http://www.domain to httpS://www.domain

But this show a very borring screen about certificate...

On good routers I use a router translation from 82 to 80, but Zyxel 642R do not have this feature...
Neither Speed Touch Pro...

If you have a different approuch I´ll apreciate it!

Thanks!

I've outlined it the best I can here:

Sorry it took me so long to reply. These are, in fact, the instructions I followed to get it to work on 5.5:

http://myezserver.com/downloads/mitel/beta/freeswan-sme55/freeswan-howto.html

Works beautifully, but my "port 80 through the tunnel" problem still persists, which I've outlined here:

http://www.chavis.us/ipsec80.html

The 192.168.100.64 machine behind the tunnel works locally, just not remotely through the tunnel on port 80 (port 81 is fine). It's running Microsoft IIS.

Thanks,
Sterling

P.S. I just tried FTPon port 21 through the tunnel to my XP Pro machine and it works great.

I think I fixed it... I disabled squid and everything works now.
