I would really appreciate it if you could help me with this.
Im setting up an internal mail server using Zimbra server 8.0.3 and i want people from outside the domain to be able to access this server which is located locally.
I have a public ip provided by my ISP and i have assigned that IP to one port of the router(Where the link from the ISP comes in) and this server is located behind that Cisco Router with a public IP 192.168.xxx.xxx.
In that router i performed Nat Port Forwarding as seen below so that mail requests from outside will be forwarded to that server.
ip nat inside source list 10 interface GigabitEthernet0/1 overload
ip nat inside source static tcp 192.168.30.254 22 41.59.xx.xx 22 extendable
ip nat inside source static udp 192.168.30.254 22 41.59.xx.xx 22 extendable
ip nat inside source static tcp 192.168.30.254 25 41.59.xx.xx 25 extendable
ip nat inside source static tcp 192.168.30.254 80 41.59.xx.xx 80 extendable
ip nat inside source static tcp 192.168.30.254 110 41.59.xx.xx 110 extendable
ip nat inside source static tcp 192.168.30.254 143 41.59.xx.xx 143 extendable
ip nat inside source static tcp 192.168.30.254 389 41.59.xx.xx 389 extendable
ip nat inside source static udp 192.168.30.254 389 41.59.xx.xx 389 extendable
ip nat inside source static tcp 192.168.30.254 443 41.59.xx.xx 443 extendable
ip nat inside source static tcp 192.168.30.254 993 41.59.xx.xx 993 extendable
ip nat inside source static tcp 192.168.30.254 995 41.59.xx.xx 995 extendable
ip nat inside source static tcp 192.168.30.254 7025 41.59.xx.xx 7025 extendable
After that i change MX and A records of my internet domain mail.example.co.tz to point to that public ip 41.59.xx.xx so that any one accessing that link will be redirected to the public ip and then port forwarded to the mail server.
So here comes the problem...after all that when i access mail.example.co.tz opn a web browser it says Unable To connect.
Am i going wrong somewhere??

hi mr jon.marshal firstly i hav set the clients with the corresponding default getway on the router subinterface. for example if a client is in vlan 10 and on the subinterface the address is 198.162.10.1, that is the one i assigned to the client secondly i have disabled firewall on my clients. but its still not worning. lastly it seems that from any vlan i can ping the switch and the router subinterfaces, also any client in other vlans can successfully ping the management vlan, but a client in the management vlan or any other vlan can not ping other vlans. help

im trying to set up a new network back at the office but im having problems communicating between vlans. i hav one router(cisco 1941) and a switch (cisco catalyst 2960g). im using the router on a stick method. i have two vlans on the switch and i have done everything according to instructions but i still cant ping from one vlan to another. the hosts in the vlan can ping the switch, router and a;; gateways but just not other hosts. the weird part is that the same configurations works fine in packet tracer. here are my configurations. just check them and lemme knw where i went wrong.
