Neoflex Data device - no bridge mode?

I've been looking around in the device's configuration and I can't find anything for bridge mode - has anyone else managed to find it?

I'm not really happy to allow an unknown device to handle my firewalling, so this is a PITA.
 
The easiest way to do this would be to use the Windows method of bridging connections.
You can achieve this by selecting the connections that you wish to bridge (in te Network & Sharing Centre ---> Manage Metwork Connections) then right click on the connection and select "Add to bridge".

Hope this helps.

Sadly I don't think it will. I'm no expert, but in order to make a bridge in Windows like that, you need at least 2 network connections. If he's plugged into the NeoFlex device via ethernet or even wi-fi, it won't help, as it's only a single connection. Most motherboards/computers only have one ethernet port.

I think he was referring to the type of bridge mode you get in adsl routers, where you can make the PPoE connection in Windows and let it dial rather than the router itself.
 
If your going to setup a firewall anyway, why not use the firewall PC as the gateway / proxy for the other PCs? We do this at work. Our DSL router has no magic configurations, but we all connect through out proxy / gateway instead...

Just a suggestion.
 
I think I misunderstood your query - let me investigate and get back to you.
 
Hi Mr Neotel

Please could you find out from your guys if it is possible to bridge the WAN (CDMA) interface of the NeoFlex router to the LAN interface. This allows a 3rd party device to establish the PPPoE session and would be a critical requirement for me to use the product.

This means that the IP that is allocated to the PPPoE session is now available directly on the dialing device and not stuck behind NAT nonsense in the router. This has significant implications when trying to do things like VPNs.

At a guess, I wouldn't think this is possible.

I assume CDMA networks, like UTMS/3G/HSPA ones, do not use/support PPPoE, just raw PPP (without the MAC header). Think about it, with the global popularity of cellular comms, have you ever seen a 3G/HSPA PPPoE modem? I haven't, they're always either a card/USB device (emulating a serial dial modem) or an IP router (with integrated/attached serial/USB 3G/HSPA modem device).

This is what I was looking to do - amongst other things, I need to VPN into my home network.
I could use the internal interface with NATing and stuff, but that's a PITA and I'd rather use the already working (from ADSL) stuff on my linux firewall. I wonder if the configuration setting to allow an interface on the neotel box to be outside the firewall would help? I'll try it when I get home.

It would be - just may require additional logic in the modem.

While the air interface may well be transporting PPP frames the device can still support PPPoE dialing. This is done by de-encapsulating the PPP from the PPPoE frames within the modem before they are offloaded to the air interface. This is done on the iBurst UTD and works seamlessly.

The problem would not be at the user end, but rather in the core at the IP access concentrators (GGSN in 3G/HSPA networks). It is not standard for them to use/support PPPoE (for 3G/HSPA the norm is PPP over GTP (GPRS Tunneling Protocol), as recieved from the base station).

iBurst networks, like DSL & most WiMax ones, natively use/support the PPPoE protocol, its part of their inherent design.
 
@ambro:
As mentioned by others in this thread it is not possible to bridge the CDMA and LAN interfaces. The device makes the connection to the network and not the pc.

@ abraxis:
The feature you are requesting is not supported by the device.

Surely the router has a VPN passthrough?

This makes it pretty useless IMHO. I am going to have to recommend going elsewhere for connectivity.
 
are you using the device in usb or ethernet mode? afaik there was a button next to the ethernet port where you choose.
 
I have just completed the setup of my home network with the Neotel MV400 outside a Linux Firewall (was using a Sentech modem using ppp-oe). Although there is a double NAT taking place, all the tests I have done have worked fine, including VPN to the office, P2P, locally hosted web and mail server. So I don't see any reason why this shoudn't work for you too...

For most purposes you can get away with this kind of setup. I however require the external IP to terminate on my router. There are a number of layer-4 protocols that cannot work any other way :rolleyes:
 
Hey ambo, just curious - are you talking router appliance, or a os based gateway/firewall? And what session types are you talking about? Maybe I can do some tests here and let you know what works? :-)
