There are 3 'consumer' APN's available to the Vodacom user base:
internet - NAT'd IP with all incoming ports blocked, i.e. you can connect to any service with no blocking or shaping of any kind, but your PC can't accept incoming connections. This is out-and-out to protect users from port attacks and scanning.
internetvpn - Routable, dynamic IP with all incoming ports blocked, i.e. you can connect to any service with no blocking or shaping of any kind, but your PC can't accept incoming connections. This is out-and-out to protect users from port attacks and scanning.
vlive - same as internet, but allows you to connect to VodafoneLive at no charge.
All the above apn's block incoming ports but have no restriction on outgoing. You decide what to do with your data.
Some users, in addition, required unsolicited incoming connections and for this the 'unrestricted' APN was created. This allows you to do things live web streaming, remote desktop support, etc. My original name for the APN was the 'hosting' APN, but it turned out to be more than that.
The danger of this APN is that it exposes your device to the greater internet and you can (and probably will) be attacked. Worse, because you pay for every byte sent or delivered to your data card, you could end up paying for the privilege of being attacked! But some people require the service and thus I asked for it to be created a year or so ago.
Another triumph for the forum, BTW!!
Initially you could auto-provision yourself via 4me but I asked for it to be removed and replaced by the relevant form, the idea is to make VERY sure a user understands the risks.
On-line, click-through would have enticed users to auto-provision without understanding the risks (and wasting precious routable IP's). We recently saw posts here where there was no need to be on the unrestricted APN, but yet, it seems, the subscriber provisioned himself in any case.
If you read the disclaimer you'll notice this is basically what it says: By using the 'unrestricted' APN you will not hold Vodacom responsible for incoming data charges. So, please ensure your firewall is up to scratch.
1) NO blocking, shaping, throttling or messing with outgoing ports, in any way, on all Vodacom APN's. This covers 99.99% of all Vodacom data users as the vast majority of applications initiate the connection from the 3G side.
2) internet, vlive and internetvpn APN's will block all unsolicited incoming connections.
3) unrestricted apn allows all incoming ports, again NO blocking, shaping, throttling or messing with incoming ports, in any way, just like outgoing.
To summarise the summary: NO shaping, whatsoever.
