Hi,
Earlier my zimbra working fine, i had 192.168.1.1 eth0 and eth1 having public ip..now i have change my isp so configure new IP etc on eth1.... mail sending and receiving working fine..even i can able to login into admin panel from outside at port 7071 but not able to open zimbra webmail at port 80 from outside after shifting to new ISP, so what is the possible reason?
