Routing local & international traffic

[Squonk]

I have been following the thread on "Splitting international and local traffic on a Linksys WRT54G" with interest but as traffic splitting is only of minor interest in that thread, I would like to ask the question here:

I am currently running Route Sentry with multiple RASPPOE connections to separate local and international accounts using a Billion BPAC7300M ADSL router in bridge mode. Running in bridge disables a lot of functions on the router including the firewall. If I add another router (like a Asus WL-520gU) using the Billion as a ADSL modem will I be able to use the firewall functions on the new router?

What I also would like to know is if there are routers (specifically ADSL routers) available that can do split routing natively. Also is there an ISP that offers split routing, surely they must be able to do this at the ISP level - or will that affect their profits too much?

1) What I do to overcome part of the firewall issue is to run my international across the WLAN and the local across PPPOE via WLAN. This already sorts out some problems for me. The only way I can see you using both routers and having a firewall with the routers running as firewalls is if you connect to two WLAN's- impractical.

2.1) There is the WRT45GL (L->Linux) on which you can do the routing (with some know-how). There are a few other routers too that I have heard of. The 54GL just doesn't have a built-in adsl modem, as it is only a router.

2.2) ISPs claim not to be able to split routing at ISP-level because they say that they do not look at packets before processing them, they are processed automaticaly and directly. I know that it is possible for it to be done, but then the systems and routing would be done in a whole new way, with some major expenses coming in for the short term.

Hi,

Thanks for the input. Looks like I will have to go the WRT way. Just seems strange to me that there is no off the shelf solution for such a common problem.

Actually it is not common at all- the problem only occurs in South Africa... other countries have a international cap at less than our local cap, so they have no need for this route splitting...
