Title: DFL-210 and Clear Wireless
Post by: theodore on May 24, 2011, 04:30:28 PM

I need a bit of help please!
I thought I would help a friends company provide secure access to their video surveillance  system by putting in a DFL-210, but I have run into a couple of issues.

They are using Clear Wireless and they don't have a "real" network internally, more like a home network, all running OSX except for two windows machines.  NO server etc...
Clear does not provide a transparent bridge, but a very poor router that NATs the assigned static ip.
The port forwarding works, but the DHCP only will provide two addresses no matter what you set it to.

I am hoping that somebody can help me with ideas on how to configure the DFL-210 to provide access to the video server via HTTP/S and remote access via VPN.

I would rather not NAT a NAT but I don't think I have a choice, but am really looking for thoughts on how to configure this firewall for the best solution.

Thanks ahead of time.
Please let me know if you need more information.
This is really a very simple network (7 machines, 1 network printer) outside of the issues that the Clear cause.
Thanks
TL

hi here are my suggestions :
1 - Check is DMZ option exist on the clear nat router.
2 - if so then set the IP address of DFL in dmz. If no then will use different setup
3 - if no dmz feature in clear router then configure DFL in transparent mode and disable dhcp in clear nat router and enable dhcp in DFL.
4 - it would be great to separate video network from data network
5 - to do so use two switches - one for data (computers) and other for video devices.
6 - connect one switch to lan interface and other to dmz interface of DFL
7 - the transparent mode will be enable between dmz, lan and wan interfaces
8 - regarding DHCP, you will need to select a scope for each network (data and video)
9 - you will be able to create vpn tunnels to access either data or video network.

Please provide more informations for network topology

for wireless purposes i would suggest going static. dunno y.. but it work better for me.. i am running 4 camera's via my dfl-210 which is just running as a firewall and i have no issues.. but the moment i enable dhcp it buggers up thw whole setup.
