We have a depot quite some distance from the exchange, the expensive internet connection is only getting 2/1Mb. This causes constant drops as soon as someone downloads anything. We have now got a 4G (Mobile internet) box set up which is getting 35/20Mb, making the internet actually usable.
We now need to route the VPN traffic through the old connection, but allowing all other traffic to use the 4G box.
I haven't been able to find much information on what needs to be changed on the configuration for this to work.
Many thanks.
EDIT: Not possible with the TZ-180 due to only 1 wan port.
