I setting up a proxy server for a DMZ with Zimbra 6.0.1 NSE.
External users can use this access :
https or imaps
I configure rules on my firewall :
External to Proxy
Proxy to MailServer
But I don't understanding inter-connection between Proxy and MailServer
If I understand the documentation :
Users connect to > 443 / 993
Proxy sent request to > 8443 / 7993 / 7072 / 389
But on my firewall the request between Proxy and MailServer use this ports :
80 / 143 / 7072 / 389
I modify my configuration with this commands (on two servers) :
./zmproxyconfig -e -w -a 80:0:8443:443 -H HOSTNAME
./zmproxyconfig -e -m -i 143:7143:7993:933 -H HOSTNAME
./zmproxyconfig -f -H HOSTNAME
./zmcontrol stop && ./zmcontrol start
No effect on my systems.
Proxy proxyies HTTP request Proxy Route lookup Handler which listens on 7072 port on mailbox server. Read admin guide for more details.
