IPsec using public IP addresses
I have to connect a VPN to another VPN, at a network I dont control, that only allow public (WAN) IP addresses.
Please look at my network setup below:
Lan Server1 –------ Router and VPN Gateway1 -------- |internet| -------- VPN Gateway2
I have control over (Lan Server1) and (VPN Gateway1)
The other gateway (VPN Gateway2) I have to connecto to using public IP addresses, I dont know why, but that is what I am told.
Lan Server1 has the following IP address
220.127.116.11 (This is a public WAN addresses NAT'ed using 1:1 NAT to this server)
VPN Gateway1 has teh following IP address
This is what the owner of VPN Gateway2 has told me:
Clients must use public IP addresses or be NAT'ed to a public IP address.
I have successfully created an IPsec VPN tunnel between two pfSense gateways, but only using the LAN address, I have never tried setting it up using WAS addresses.
I tested between two pfSense IPsec gateways by setting 18.104.22.168 as local subnet on the local gateway and as remote subnet on the other. In the Status: IPsec I see a connection with a green arrow, but I can not get any connection of any kind between the two networks.
I do not know if I am doing it right or if this even makes sense, so any help would be appreciated.
Nobody knows if it is possible to connect two servers with NAT'ed WAN addresses ?
