Firmware: DD-WRT v3.0-r47381 std (09/08/21)
my pppoe R7800 always disconnect after see like this

Sep 14 23:10:57 shafax4s daemon.err dnsmasq[2099]: failed to read /tmp/resolv.dnsmasq: Permission denied
Sep 14 23:10:57 shafax4s daemon.warn dnsmasq[2099]: no servers found in /tmp/resolv.dnsmasq, will retry
Sep 14 23:12:31 shafax4s daemon.err dnsmasq[2099]: failed to read /tmp/resolv.dnsmasq: Permission denied
Sep 14 23:13:03 shafax4s daemon.err dnsmasq[2099]: failed to read /tmp/resolv.dnsmasq: Permission denied
Sep 14 23:13:43 shafax4s daemon.err dnsmasq[2099]: failed to read /tmp/resolv.dnsmasq: Permission denied

my setup just change Connection Type pppoe like Alozaros did
Connection type: PPPoE
Username:xxxx
Passord:xxxx
Static DNS 1 = 203.142.82.222
Static DNS 2 = 203.142.82.222
cause isp must be use their dns

Additional Dnsmasq Options
server=203.142.82.222

add to DNSmasq additional box
no-resolv
server=203.142.82.222
server=203.142.84.222

check via telnet or ssh
cat /tmp/resolv.dnsmasq
