- Thread starter Necuno
- Start date

Guys, as I've said before, I think you're confusing products again. I believe the following 2 are being refered to interchangably ...
1. IS Business ADSL
- uncapped
- 5 static IPs
- requires router that can do L2TP tunneling (Cisco 8XX or Billion 7404VGO)
2. IS Business ADSL Express
- uncapped
- 1 dynamic IP
- can be used with any ADSL router
I dont believe you will be able to get bridging working with 1. however 2. should be no problem at all.

There was a post saying the actual (cisco) routers can do this, The ADSL bridging should be on a different layer (transport) to the tunnels etc so i dont see why this cant happen apart from IS not wanting to do it and us not having the login
Regarding is express is that product still available? I remember reading that its not but i cant find the post on this thread

It is, however the IP addr assigned by the PPPoE authentication for ADSL is not globally routable on the Internet. Only the 5 static IPs are, however only via the L2TP tunnel.
Doubt IS would ever give out the L2TP username & password
Last problem, I doubt IS's LNS (L2TP termination router) is configured to support PPPoE relay over L2TP, so there is no way you could complete authentication from a remote (bridged) PPPoE client.
Roman, as far as I know there is PPPoE connection running from the Cisco router which gets a dynmic IP routed to it over IPConnect. On top of this there is another tunnel (not sure if it's L2TP as you say), but there should be nothing stopping one from establishing another PPPoE connection through the router to another ISP - that is, if you can get into the router. Doesn't seem as if anyone has tried a password recovery on one of them yet.

JayM, you're right ... was looking at this with blinkers on. Thought Necuno was looking to get unshaped on IS by using bridging to circumvent any IP traffic shaping functionality within the IOS config, not by using a secondary SAIX account.
Of course if you can get the enable password, it would be easy peasy to create another PPPoE connection and direct some traffic down it with static routes, while leaving the original PPPoE & L2TP connections untouched.

i'm quite sure one would keep the router password for himself 
any mention of it and your isp will fix the pwd...
IS says with the billion router its impossible to have it pared with another router aswel as they will not allow any other access through the router than its default setup by them.
fancy that...
last solution is getting another telephone line and adsl rental or switch the damned router off and plug my personal one back in.
in the end its a loose loose situation even if you can easily afford uncapped.

In my personal opinion south african broadband has reached a new low. And by broadband i mean uncapped. **** three months ago it was R999 for 512k
special from openweb that always downloaded at 4mb international and local. NOW it's over R3000pm for 100Kb/s and its not your own router its their sterile POS.
What will happen is one of the isps will step up with something new then the rest will buckle, but until then i think they are enjoying the cashcow.

Two things would need to be true to get the above working unfortunately - 1) IS must not be using "no service password recovery" and 2) The code must be 12.4(15) or later to support adding a 2nd PPPoE connection to the ATM interface.
If password recovery is enabled, and the version of code is earlier, it may still be possible to enable bridging to allow a PPPoE connection through the device from another router/PC. I don't have access to a business DSL router in order to fiddle.
In my opinion, here's a better solution "home-brew business DSL":
- Cisco 837/877 with 12.4.15(T) or later
- 3 10GB SAIX accounts for international
- 1 2/28 IS account for local
Comes to about the same price and should be enough bandwidth for most requirements, and SAIX>IS for international. Alternatively, you could use Telkom accounts instead of SAIX. With some minor trickery Cisco can even auto-rollover the accounts.

Good point, I take running the latest (actually early release) versions for granted.
Yes IS assigned. Jogging my memory a bit, I think the ADSL assigned IP is actually globaly routable but under the same traffic policy restrictions as the Express product. The IP assigned on the L2TP tunnel is not routable, only the 5 static IPs (bound to the loopback) which are also free from (excessive?) traffic shaping.
The LAN IP range is NAT overloaded onto the first static IP while the other 4 can be used for static 1to1 mappings for mail & web servers etc. In essence the aim of the IS Business ADSL product is to provide leased line type functionality over (Telkom restricted) DSL technology.

Correct on most counts, but I don't think the 5 static IP's are bound to the loopback, nor overload natted to the ethernet IP - they are usable simply because they are on the same subnet as the Ethernet IP. The 5 IPs can be assigned directly to hosts, and are not NATted on the router. I used one of these briefly a few years back, and outgoing connections came from the same source address as was assigned to the host.

Suppose they have different variations of the config for differing stiuations. I've seen sites with many more than 5 PCs and sometimes servers on 192.168 private addresses running solely behind the Cisco.
Here the main static IP is bound to the loopback and this interface is referenced in the nat overload command, with ip nat inside=eth outisde=L2TP virtual). Other static nat commands are used to map inbound port 80, 25 etc. on the other statics to servers on the inside.
