I have the following network setup:
- Zyxel USG 200 Firewall which also acts as DHCP server
- 2 Switches
- 2 Wifi APs (Zyxel NWA3560-N and WAC6503D-S) with NAT and DHCP disabled
The clients (mostly MacBooks) are normally connected to the switches by cable. The problem is that if you have to leave the workplace (e.g. go to a meeting room) and disconnect the ethernet cable, the connection breaks. So file transfers stop, SAPGUI closes the connection and with it all open windows, database connections and VPNs are interrupted etc.
I would like to avoid this. So when disconnecting or connecting the ethernet cable, programs should not notice the change.
I found a way to do this: assign the same IP address to both the ethernet and the wifi connection. Problems:
- It does not feel like a good thing to do.
- The DHCP server does not allow to assign the same IP to two different MAC addresses. So I have to enter them manually on the client. As we are often visiting clients, it is cumbersome to always change the IP settings.
Is there any "best practice" way of setting up such a scenario? I was thinking about setting up a tunnel or bridging the interfaces, but there probably is a much better way for doing this.
