I must be ignoring something really basic in my configuration. Here is the scenario.
I have an EdgeRouter X in my home running firmware version 1.9 in a very basic vanilla configuration:
eth0 -- WAN using DHCP
eth1-eth4 - configured as switch0 192.168.1.15/24
This configuration was set up using the basic wizard
Everything work very well -- fast and stable. There are more network switches and two wireless APs downstream off switch0. Some clients use static IP addresses and some rely on DHCP. Works flawlessly.
eth4 connects directly to an outdoor wireless AP that supplies my garage and guest studio underneath with wifi. The AP address is 192.168.1.13. It's configured as a true AP -- does not do DHCP or NAT.
I was hoping to turn the outdoor AP into a dedicated guest wifi network so that I could potentially rent out the studio appartment. My security concerns are to block access to my other internal clients on the 192.168.1.0/24 network when associated with the outdoor AP. So I decided I will just create a second separate LAN that is dedicated to eth4 and the outdoor AP.
Here is what I did:
1.Change outdoor AP address to 192.168.2.13
2. Change outdoor AP gateway setting to 192.168.2.15
3. Remove eth4 from switch0 in the switch0 configuration
4. Configure eth4 with an IP address of 192.168.2.15/24
5. Verify that the above action results in the addition of a static route in the routing table that's connected and links interface eth4 with destination 192.168.2.0/24
6. Add a DHCP server for 192.168.2.0/24 with a router address of 192.168.2.15 and a (temporary) DNS server 8.8.8.8. The DHCP server is active and configured for 192.168.2.100 to 192.168.2.200
At this point I am under the impression that the second LAN on eth4 should be working. But I cannot associate with the the outdoor AP becuse it is not willing to give me an IP address via DHCP. If I configure my client with a static address of 192.168.2.50 then association works.
Can anyone tell me where I am missing the boat here???
I can post the config file but to me the above description seems clearer since I beginning with such a simple config.
Thanks for any and all advice!!
