ACCESS TO SERVER from internal BY EXTERNAL DOMAIN

[pgbuz]

After some days of study I discovered the problem existing with zeroshell and not with more simple routers. Seem that there is a solution http://zswiki.pan-am.ca/wiki/NAT_Hairpin but I’m not so able and I ask help. I think that in a configuration standard as mine can help a lot of people.

router zeroshell ip 192.168.3.1 – eth0
external ip 44.44.44.44 – eth1 domain example.com
internal server1 192.168.3.11 – eth0 https port 443
internal server2 192.168.3.12 – eth0 https port 443
NAT enable eth1 only
firewall disabled, dns disabled

I use from external to access server1 https://example.com:443
and https://example.com:4433 to access to server 2

With virtual server rules any/eth1:443 to 192.168.3.11:443 and any/eth1:4433 to 192.168.3.12:443 I don’t have problem from external, but nothing to do from internal. I tried with virtual server rule 44.44.44.44/eth0:4433 to 192.168.3.12:443 but I cannot access to servers from their LAN. I think a nat problem and I think that I have to insert in zeroshell a rule using an iptable script. Can some people help please?
Thank you

No people helped me but I found the solution. I hope can help.

In Scripts/cron — NAT and VIRTUAL SERVERS:
iptables –table nat -A POSTROUTING -s 192.168.3.0/24 -d 192.168.3.11/32 -p tcp -m multiport –dports 443 -j MASQUERADE
iptables –table nat -A POSTROUTING -s 192.168.3.0/24 -d 192.168.3.11/32 -p tcp -m multiport –dports 443 -j MASQUERADE

In router — virtual server rules:
any/eth1:443 to 192.168.3.11:443
any/eth1:4433 to 192.168.3.12:443

Now my last problem is that if I call https://example.com:443 from internal, I arrive on zeroshell web management and not on 192.168.3.11 server.

Did you find the solution for this problem? I want to do the same.

[pgbuz]

yes, the upper solution works. Has been a miss config that sent me on management page.

i think you over took it, it may be very simpler to just not put any ip nor interface as source, and your virtual server will be availbale from inside too.

in your case, it should be any/any:443 to 192.168.3.11:443
