Hi, I just got a C800 series router running on static internet IP at the WAN port and having 2 VLANs as inside interface. Ports forwarding has defined for Internet to the application in order for Internet users to access the application. Due the application limitation, the client program has hardened with public IP to access the server. is there anyway that the user can access the the server thru public IP even though their connected to internal network? Currently, the user cannot access the server once they back to office unless change the reconfiguration the client software back to private ip. probably you will have a better view by refering to below.
WAN IP: 188.8.131.52
VLAN 10: 192.168.1.0/24 (SVRFARM)
VLAN 20: 192.168.2.0/24 (USER)
application server IP: 192.168.1.99/24
application client software harden with 184.108.40.206 TCP port 9090 to access from Internet
Port forwarding: 220.127.116.11 TCP port 9090 to 192.168.1.99 TCP port 9090 (allow user to access thru Internet)
User have to manual reconfiguration the client software from 18.104.22.168 to 192.168.1.99 once he is connected to VLAN 20.
I'm wondering is it posibble to use ip nat inside destination just to translate destination IP back to private ip for the traffic from VLAN 20 to VLAN 10?
hope that someone can help me... thanks.
