S2S VPN mit zwei Fritzboxen mit selben Adressbereich

dimon over 4 years ago

Hi,

ich habe zur Zeit eine Fritzbox mit S2S VPN an meine UTM angebunden. Die AVM hat Standard Adressbereich (192.168.178.0/24).

Jetzt möchte ich eine weitere Fritzbox mit S2S VPN anbinden. Diese hat aber auch 192.168.178.0/24 Netz.

Wie kann ich es auf der UTM Seiten NATten, damit ich Zugriff auf beide Netze habe?

Hallo Dimon,

Schaue mal diese zwei Fäden an: VPN between same subnets & More VPN between same subnets

VPN between same subnets Link is down.

My Problem is, that i have to use 1:1 NAT on BOTH sides. But on another side is just a AVM Fritzboox which cant 1:1 NAT.

Thanks for letting me know, Dimon - it's now How to tunnel between two UTMs which use the same LAN network range.

It looks like you might want to change your Addressbereich. My usual recommendation is for internal subnets to be in the 172.16.0.0/12 range. Reserve 192.168.0.0/16 for public hotspots and home users. Reserve 10.0.0.0/8 for giant multinationals, ISPs, etc.
