Work VPN not working

[Benjo_sc]

Hi,

My partner and I work at the same company, and work from home. We both connect to our work through a VPN set up by our IT department. However, we can only connect to the VPN one at a time and get an L2TP error.

Set up is...

Hub 3 router, in modem mode, connected to a Nighthawk router. One of us can connect at a time as noted above.

As a test I put the Hub 3 back in to router mode, we could both connect to our work VPN at the same time.

Previously, when worked for different companies we could connect to the separate VPNs. So it makes me think there is a setting within the router blocking us or being read as a conflict. Any help is appreciated.

I would stick with my Hub 3 in router mode, but it's not great for my house (all solid walls and comes in at the furthest corner - also tried power line, electrics aren't up to scratch)

The fault appears to be : Nighthawk router not working with dual VPN.

Hi,

Yeah, it's not necessarily the nighthawk as my TP link one (nighthawk bought yesterday to replace it) was not allowing any VPN connection at all, had to use power line. So it's definitely something with the first router after the modem, just can't work out what it would be....

If you want you can test to my VPN link below to see if two links works to me

My guess is the NAT is not offsetting the source port on the WAN IP to the same destination IP for like 192.168.0.10 by 500 to 500 and 4500 to 4500 with the 192.168.0.20 1024 to 500 and 1025 to 4500

Hi, I am trying to get a response from them, thanks.

I'll suggest this to my IT team at work and get them to try it, work laptops are on lockdown 🙃

A 3rd party router firewall that is too aggressive ?  
Test with Router Firewall severity reduced / disabled, does the situation improve.
