Hi,

I wanted to create wlan with an own dhcp server and I did it with this Multiple WLANs documentation.
Unfortunately I am not able to browse the internet. Therefore I executed -> iptables -t nat -I POSTROUTING -o `get_wanface` -j SNAT --to `nvram get wan_ipaddr` but didn't help.

I then want to use dnsmasq to use specific dns servers for specific requests.

thx trull

Hi,

I use DD-WRT v3.0-r40559 mini (08/06/19)
on Linksys WRT54gl v1.1.


The problem is I have a network

FB (DHCP Server) <-> AP CPE510 <-> Client CPE510 <-> DD-WRT

and I want to dnsmasq some requests so I thought I can create an own WLAN (with own DHCP Server) on the DD-WRT and dnsmasq special requests?

thx




thx

You hopefully have read the forum guidelines and discovered that you should not use 40559, that is an old an crappy build.

Not saying your current problem is related to this crappy build but other problems will crop up. So first get a recent and better build as described in the forum guide lines.

Attached my notes how I setup a VAP but there are different ways to do so, this is just my way Smile

Hi,

I also tried this approach but also got no internet access.

I have already the latest firmware installed -> 40559 there is no newer one.

thx trull

Read the disclaimer. Read the firmware FAQ. Read the Broadcom build threads.

Perhaps you should read the forum guidelines I pointed to.
