hello
I am trying to setup a vpn connection  between two sites.

SiteA: Cisco asa5512x configured
SiteB: RV180w  configured

The  issue is that , At  the SiteB with Cisco RV180   I cannot change the Local  Internet IP address to the  Public  and  is getting the  internal  IP address by default


What is the issue on that?

Can  anyone help me?

Is the local (external) Internet IP for the site with the RV180 static or DHCP. Either way, I do not think you can change it. You need to set the RV180 IP as the remote IP at the Cisco site that is connecting to it.

I assume you set the two VPN phases and authentication.

Site to site requires Static. If your DHCP changes infrequently (once a year or thereabouts) then it can work (I do that).  But you need to put that IP in the Cisco site. Also you need to put the Cisco site IP in the RV180 site.

Each end of the VPN must know the IP of the other end. Also both ends cannot be DHCP. That is not likely to work.

If the DHCP of the RV180 end changes every time you connect, you cannot use it for VPN.

Here is a setup for a Cisco RV042 which is roughly the same setup as for the Cisco RV180.

Note in the Local Setup area the first IP address you can see (in the last octet) that it is greyed out. This is the external IP address of this end. It is set by the modem and the WAN setup of the router and it cannot be changed.

The second IP address is the local internal IP address and it can be changed but it has to work together with the internal IP of the LAN setup.

Note in the Remote Setup area, the first IP address is the external IP of the other end. The second IP is the internal subnet of the remote end.

Is this what you are seeing.

according to your screenshot the local IP address  must be the  public right?? In my case it is  192.168.1.133 which is the private  given by modem.....:(

Thank you. This is clearer now.

You need to put the modem in Bridge Mode and then set the WAN DHCP in the RV180 to the external IP provided by your ISP. You may need the ISP to help you. This will make your RV180 the main router in your network.
