    You should try to put the ISP router in pass through or bridge mode so the public IP address is directly attached to the sonicwall instead of having to deal with port forwarding on the ISP router.

    You mean bridge mode between ISP router and sonicwall firewall? then should i use public Ip from ISP router for site to site vpn?

    Hey @ipatel

    Please have a look into the following KB which explains the setup of a site to site VPN in Aggressive Mode where one site (Site A) has a public IP and the other site (Site B) does not. Also, as @Overflow2021 indicated, to use public IP on Site B, you need to configure your ISP Modem/Router in pass-through mode or bridge mode.

    Thanks @MustafaA

    and which IP should I use remotely login?

  • MustafaAMustafaA SonicWall Employee

    If your ISP box is in bridge mode, then you should be able to access your firewall with the public IP address. You should do packet capture on Packet Monitor tool to trace the incoming traffic.

    Thanks for the clarification

    and ISP box WAN IP and Sonicwall WAN IP will be same if my ISP box is in bridge mode?
