Hi all,
my first router AVM is connected to Telekom VDSL. The 2nd router VR2600V is connected to AVM as WLAN-Router.
Address AVM: 192.168.178.1 VR2600V: 192.168.178.2 DHCP: 192.168.1.1
If I am in the WLAN network of AVM I can't reach 192.168.178.2 and 192.168.1.1
If I am in the WLAN network of Archer I can reach 192.168.178.2 and 192.168.1.1

What did I wrong in the setup of Archer?

TIA - Soenarto
