I need to configure Cisco 1841 to translte public IP ( 22.214.171.124) to the private IP (10.0.0.253)and vice versa.I am using ADSL2, PPPoA and Dialer interface configured for NAT overload/PAT.
Public IP 126.96.36.199 sholud be translated to 10.0.0.253 which will use to build the VPN tunnel to the remote ofice.
To build the VPN from the remote office, remote office(sonicwall) will use public IP 188.8.131.52 but when it will hit the NAT router it should get translated to Private IP 10.0.0.253/24 which is a Sonicwall LAN IP.
Can you please advise if that is possible and what configuration is needed.
Remote Office----->Inernet----->C1841----->Sonicwall------>LAN Switches------PC/Servers
Do I ned to create two NAT statments, one for inbound and one for out bounds traffic? ANy sample config will help.
Will SonicWall be pingable from the internet using IP 184.108.40.206 ?
Many thanks for your time and support.
in this example We need to publish many internal services (web, smtp, ftp…) using just one public IP address (220.127.116.11)
ip address 192.168.0.254 255.255.255.0
ip nat inside
ip address 18.104.22.168 255.255.255.240
ip nat outside
access-list 1 permit 192.168.0.0 0.0.0.255
ip nat inside source list 1 interface serial0 overload
ip nat inside source static tcp 192.168.0.5 80 22.214.171.124 80 extendable
ip nat inside source static tcp 192.168.0.6 25 126.96.36.199 25 extendable
ip route 0.0.0.0 0.0.0.0 188.8.131.52
