well i am on r27600 and so far everything is working but when try to use cache-size and i do DHCP renew lease on my Client Computer it takes around 2-3 min to apply.. i looked around the forums regarding DHCP lease issues and i haven't found an answer for this. (including older Revisions) tested older revision such as r27506 - same issue

? so in newer versions the cache-size cannot be added coz it already in the config? how then am i supposed to override the default? edit the conf file itself? + i haven't been able to find it via telnet etc folder it not there..

well you can always modify the conf file and restart dnsmasq with a startup script sleep 10 sed -i '/cache-size/d' /tmp/dnsmasq.conf echo 'cache-size=5000' >> /tmp/dnsmasq.conf killall dnsmasq dnsmasq -u root -g root --conf-file=/tmp/dnsmasq.conf do not restart the service as it will recreate the config file. you need to modify, kill and restart. FYI /etc is read only

r28393 cache-size is missing from dnsmasq.conf unless its manually entered, dnsmasq site* says default is 150 when not overridden. if i didnt specify a cache-size & default for ddwrt is still 1500, shouldnt it be in the config as 1500?

we set cache-size now through commandline argument, config params override commandline params

-c, --cache-size=<cachesize>
Set the size of dnsmasq's cache. The default is 150 names. Setting the cache size to zero disables caching.
