Checkpoint 1430 and multiple internet connections

[KikoLlanos]

Hi, everybody.

I'm having problems with my Checkpoint 1430 and the nat/wan addresses with my internet provider, Movistar.

My Movistar provider in addition to internet offers me voip. The internet (data) connection goes through vlan 6, and the voip connection goes through 3.

The internet connection (ip 83.x.x.x) works perfectly, the problem is in the voip connection.

To configure the VOIP connection I use a Cisco SPA112, correctly configured and connected to the LAN6

I add a manual route for everything 10.0.0.0/8

And this is where the problem comes. Sometimes, the Checkpoint undoes the nating and goes out to WAN.3 with the IP provided by DHCP, a 10.x.x.x

But other times, like now, it's coming out with the ip 192.168.1.2 (strange!)

Can you think about what might be happening? How can I force it to take the IP address of the WAN.3 DHCP?

Thank you

Make sure you're on the latest firmware release, which you can get from here: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut...
If it's still happening after that, please open a TAC case.
