Thanks for the information. It appears to be working now after some tweaking.
For others who want to do the same, here are the steps I used (there may be better/other ways) to setup static IP addresses for a single 2.4GHz and single 5GHz Guest Wifi network. Note this assumes one has created the Guest WiFi networks in the Asus Merlin administrator interface. Obviously have the YazFi script installed, configured and running properly with the guest WiFi clients connected to the guest WiFi network(s). And the below assumes you have an SSH connection to the Asus router.
Edit/create the Dnsmasq.postconf file:
Code:
nano /jffs/scripts/dnsmasq.postconf
Add in the following code, with your guest client static IP address, MAC address and device name. In my case (in the example below) I have two static IP addresses. Add additional lines for additional static IP addresses. Note: Make sure to use the correct IP address range from the YazFi config file. In my case the main Asus router IP range is 192.168.2.x. The guest WiFi use ranges 192.168.3.x and 192.168.4.x respectively. Replace the "XX:XX:XX:XX:XX:XX" with the guest client MAC address.
Code:
#!/bin/sh
CONFIG=$1
source /usr/sbin/helper.sh
pc_append "dhcp-host=XX:XX:XX:XX:XX:XX,192.168.3.2,devicename" $CONFIG
pc_append "dhcp-host=XX:XX:XX:XX:XX:XX,192.168.4.2,devicename" $CONFIG
Change dnsmasq.postconf file permission so it can be run when the router is rebooted:
Code:
chmod +xxx /jffs/scripts/dnsmasq.postconf
Note: Failure to appropriately change the file permission will result in the Dnsmasq.conf file not being updated with the guest static IP information.
Reboot the router.
After router reboot, one can check if the Dnsmasq.conf file was updated with YazFi guest wifi static IP’s (see end of file):
Troubleshooting:
Initially I ran into a problem (somehow) where the WiFi settings got corrupted on the Asus router when first working through setting up YazFi and trying to set a guest static IP. The router wired LAN network worked when I set a static IP address on a wired client, but wireless clients could not connect to WiFi. The workaround was to use a wired network client configured with a static IP address in the client OS and then edit Dnsmasq.conf file if error to remove the YazFi content and YazFi guest static IP conetnt and reboot the router:
If that doesn't work one may have to remove the YazFi script through the YazFi GUI and reboot the router. Then one can try the process again by installing the YazFi script and performing the actions previously detailed to set a guest static IP address.
Additional Notes:
The underlying reason for using YazFi was due to an Amazon Echo connected to the Guest WiFi failing to work properly when connected to an Asus router running Merlin firmware that is configured; using Pi-Hole for DNS, Advertise router's IP in addition to user-specified DNS set to No, and the Guest WiFi Access Intranet setting set to Off for each guest network. The problem was the Echo couldn't run DNS requests through the Pi-Hole so the request would fail. The previously detailed steps above now allow the Echo to work properly and contact the local network Pi-Hole for DNS requests.
Hopefully this info will help others who faced a similar problem with a Guest WiFi device.
