21.1 Legacy Series / Multiple 1:1-NAT with multiple DHCP
« on: February 08, 2021, 07:27:58 pm »
Newbie question here...
I'm trying to do the following:
My ISP does not provide static IPs, but multiple IPs via DHCP.
I have two Synologys which I want to be externally accessible (Ports 80,443, DynDNS), both are on the LAN.
I tried the following:
Attach 3 Ports to the ISP-Side (WAN, SYNO1, SYNO2)
Assign Alias-IPs for SYNO1 and SYNO2
1:1-NATs from Alias-IP1 to SYNO1 and Alias-IP2 to SYNO2.
But no luck...
It works if I use the DHCP-Adress for 1:1-NAT, but as this address can change this is obviously not an option.
Can anyone point me in the right direction?
Thanks
Lucas
