I have DD-WRT v3.0-r55630 std (04/03/24) running on a wrt3200acm and I have the following error with the /tmp/dnsmasq.conf which is generated from the default factory settings for dnsmasq


My /tmp/dnsmasq.conf is as follows


Code:
interface=br0
resolv-file=/tmp/resolv.dnsmasq
dhcp-leasefile=/tmp/dnsmasq.leases
dhcp-lease-max=190
dhcp-option=br0,3,192.168.1.1
dhcp-authoritative
dhcp-range=br0,192.168.1.100,192.168.2.33,255.255.255.0,1440m
bogus-priv
conf-file=/etc/rfc6761.conf
clear-on-reload
stop-dns-rebind
dhcp-option=252,"\n"
cache-size=1500
dns-forward-max=150


which is generated from the following default factory settings


Code:
Enable dnsmasq: Enable
Encrypt DNS: Disable
Cache DNSSEC Data: Disable
Validate DNS Replies (DNSSEC): Disable
Check Unsigned DNS Replies: Disable
No DNS Rebind: Enable
Query DNS in Strict Order: Disable
Add Requestor MAC to DNS Query: Disable
RFC4039 Rapid Commit Support: Disable




My error log is as follows


Code:

If anyone can suggest a fix I'd appreciate it.

I'm sure a screenshot of Setup -> Basic Setup tab would reveal the obvious error in configuration as already pointed out by @mrjcd.

Those are not the default settings.

You put in wrong settings, to start at 100 and then with 190 clients you will go over 254.

You also do not enter anything in the Gateway or Local DNS fields in a normal scenario. Further details required.

Furthermore having a single ip address as time server is also not recommended.

Do not stray from the path ( = default settings ) unless you know what you are doing Wink

To give you a short explaination:
The subnet itself and the number of usable IP-Adresses is defined by the Subnet-Mask. In your case, Subnet-Mask is 255.255.255.0 or /24. That means you can use IPs from .1 to.254.

In the DHCP Mask you put in 190 IPs for DHCP, starting at IP .100. So you are above the usable range from .1 to .254.(The GUI should deny these kinds of wrong entries)

If you need 190 DHCP-IPs you can set the Start-IP to .64 or below (you put in .100).

OR, if you also have a greater number of static IPs (over 63), you have to take another Subnet-Mask.
With Subnet-Mask /23 you can change the DHCP-Starting-IP to 192.168.0.1 and keep the 190 DHCP-Users.

You can play around with this Subnet-Calculator to understand:
