Strange. We only implemented NAT in the last week or 2 and only in Gauteng.
I have the same issue. The problem is only in Gauteng thou. In Cape town I have no issues with VPN.
Only been having the issue the last few weeks. And only in Gauteng.
This change by Vodacom has left our company with a major problem. We are in construction and use most of our 3G connections with a combination of Huawei B683's and Hauwei B970b 3G routers. They are hooked up to a Cisco firewall unit to create a tunnel thru to our office. Now all of a sudden with this change they will just not connect. We have figured out the 41.x.x.x and 10.x.x.x issue, however this is transparent to the user and they cannot even access the Huawei units as all their traffic is tunneled thru to Head Office via the VPN, no internet breakout for them on their network. Also one of our directors are very unhappy as his VPN is only working intermittently from his 3G USB Stick.
Surely Vodacom should have let their customers know about this changes.
Can someone from Vodacom please paste the easiest way to get this resolved. From what I understand fo the unrestricted APN is it will allow traffic into that IP as well, which could cause high bills. Vodacom actually has you sign documents for this. Aslo I have about 25 sims like this.
As long as your configure your routers' firewalls to block incoming traffic, you will be OK.
Indeed from a hacking point of view yes, but from an idiot doing a denail of service attack on you being blocked by your firewall... not!
That traffic still has to hit your firewall and get blocked.
I've used the 'unrestricted' APN on a couple of SIMs since about 2007 and never had such a problem. If you are worried about high bills, make sure you only use pre-paid SIMs.
Call 155 and get the InternetVPN APN provisioned on the SIMs. Then change the settings on the various terminals to use the InternetVPN APN.
Changing to this InternetVPN APN does not seem to work as they still seem to use the same IP pool.
This post by Vodacom Data seem to confirm it.

As discussed telephonically, your SIMs need to be provisioned for the InternetVPN APN first.
Has anyone actually got the InternetVPN APN setup?
I has told by Vodacom that the InternetVPN APN has been discontinued when the Unrestricted APN was introduced.
No apparently we need to get out own private APN.
This is getting beyond funny with the amount of phone calls I get saying VPN doesn't work.
Wonder if we shouldn't start buying MTN 3G cards instead.
Years ago we did not have enough public IP's so we had to use NAT and to overcome the VPN problem, created the InternetVPN APN.
Then we got a crapola allocation of IP's (thanks Ambo!) and could retire the InternetVPN APN.
Unfortunately we're now back to square one and have run out of public IP's, so it's back to NAT and thus the InternetVPN APN got reintroduced in the last week or two.
So you might run into someone who remember the InternetVPN APN and do not yet know it's back. Which it is.
Just insist you want it and if you get any grief send them to me.
Thanks,
I will.
We have a dozen or so Gauteng VPN users and, in addition to the 10.x.x.x range, no one can connect when they receive an address in the 41.13.x.x range. I've tested this extensively and can confirm the problem. Is this a known issue? Will switching to the InternetVPN APN solve the problem?
Can you give more info please:
- Could they connect in the past, but now cannot connect?
- Can they connect with other networks, i.e. is this only on VC?
- You sure the PC setup is correct?
- Do you use non-standard ports, etc?
