I have a WRT54GS v7.2 Running the DD-WRT Micro FW.

I created a virtual interface for open Wi-Fi for friends but to keep my network private.

This Virtual Interface will not allow internet access. Only "limited connectivity" as windows puts it.

These are the settings on the Virtual Interface:

H

Wireless SSID Broadcast Enabled
AP Isolation Enabled
Network Configuration Unbridged
Multicast forwarding Enabled
IP Address - 192.168.2.1
Subnet Mask -255.255.255.0

You are using sp1 and not reading the announcement, me thinks...

I do have Firmware: DD-WRT v24-sp2 (05/21/09) micro.

I followed the instructions at this video
http://www.youtube.com/watch?v=Jd_nxZCvnHY
Every setting seemed to match up.

The computers that attempt to connect get limited access. No internet access.

Also it seems to cause problems for the WIRED network with those settings.

Did you read the linked thread and follow the links to the wiki? Sounds like an encryption issue. Remove all wireless security and try again.

Set your passphrase the same on both and try it. If it works that way then the famous "NAS bug" has bitten you.

There is a known bug in the NAS that prevents Bridged Virtual Interfaces from working unless the passphrase is the same. If you are in un-bridged mode, well, I haven't tested that one.

Ok... I dropped encryption....

NEITHER ONE would get internet access...

These are the settings I have on the router...
DNSMasq Options:
interface=wl0.1
dhcp-option=wl0.1,3,192.168.2.1
dhcp-option=wl0.1,6,192.168.1.1
dhcp-range=wl0.1,192.168.2.100,192.168.2 .200,1440m

Firewall Commands
iptables -I INPUT -i wl0.1 -m --state NEW -j logaccept
iptables -I FORWARD -i wl0.1 -o br0 -j logdrop
iptables -I FORWARD -i br0 -o wl0.1 -j logdrop

the IP for the virtual is 192.168.2.1
the IP for the physical is 192.168.1.1

I added WPA personal TKIP to BOTH same passphrase and the virtual will not connect.

also just to restate with those settings for the firewall and DNSMasq the WIRED connection becomes an issue.

This is an interactive tutorial and will allow you to enter your parameters making custom scripts for you to try. Give it a whirl and good luck.

VERY NICE! Thank you! :handshake:

One final question:
It is not a life or death situation...
I would however like to setup a "portal" where there is a basic notice like

This connection is subject to be disconnected at anytime should the need for bandwidth arise

The use of this connection for illegal activities will not be tolerated and violators will be banned.

etc. I am aware that the page its self would be html (i assume) and am fully capable of writing that up. How would I go about setting up the router where once connected, when the user goes to www.urlofchoice.com that page is displayed first?

(--MODERATORS-- feel free to move if this is out of place)

--Edit--
In case its relevant to router settings I do not intend to use username/password logins just an "I accept" or "Go to Internet" button.

This is an acceptable forum to discuss this issue in. Wink

Does anyone have any ideas for a captive portal on my WRT54GS?

This worked perfectly for me, thank you very much! I had to go through several guides, this one finally worked.
I am running
DD-WRT v24-sp2 (03/27/14) std
(SVN revision 23808)
on a TRENDnet TEW‑818DRU

Hopefully this will appear in google searches and save someone else some time.
