Merlin 384.5 vlan DHCP problem?

[Bill Lee]

Greetings all. Newly joined after reading for a while. Bought an ASUS RT-AC86U B2 and have been mucking around trying to create a separate vlan with it's own DHCP.

robocfg works, and I can create the interface and assign it a .1 IP that I can successfully ping within the SSH session. However, I cannot get a DHCP server to hand out IPs on the new vlan that match the new subnet IP. I have included iptable statements for the DHCP

iptables -I INPUT -i vlan10 -m state --state NEW -j DROP
iptables -I INPUT -i vlan10 -p tcp --dport 53 -j ACCEPT
iptables -I INPUT -i vlan10 -p udp -m multiport --dport 53,67 -j ACCEPT

And then set up dnsmasq

interface=vlan10

dhcprange=vlan10,192.168.5.100,192.168.5.254,255.255.255.0,86400s
dhcpoption=vlan10,3,192.168.5.1
dhcpoption=vlan10,6,192.168.5.1,8.8.8.8

I noticed in the Merlin version I installed that the "dhcp range" part is missing the "-" (dhcp-range, dhcp-option) that I see in previous posts. The version I am using won't take those settings unless I remove the "-", but I don't know if that is a modification that hooks up properly on the back-end. All I know is that the DHCP never properly assigns an IP for the subnet.

Any thought on addressing the problem is appreciated.

Edit: I am doing all this at the CLI for now until I can get it to work, then will try adding scripts.

Well, I restored stock firmware, tried again, and still no-go. So must be something I am leaving out in the commands/setup. Also, the stock firmware likewise does not accept "dhcp-range" and "dhcp-option", but only the setting names without the "-".
Soldiering on with more research on proper commands and syntax....

Got it working. Separate vlan on port with DHCP assignments from specified range. Just need to add it to /scripts and /configs.
If you are new to this (as am I) I would recommend using WinSCP (even if in VM) - it is just easier (IMO).
