IPSEC VPN connection to Netgear Prosafe VPN FVS114 - connects but stops pinging after a few seconds

Jake

I am trying to replace my Watchguard XTM505 VPN Firewall with an XG125

I have updated firmware etc. (SFOS 16.05.7 MR-7)

The branch office device is a Netgear Prosafe VPN FVS114

I have had a VPN setup between the Watchguard and the NEtgear for years.

I can hook the Watchguard back up and the VPN fires up no issues.

I am trying to leave the branch office settings alone for now

I have followed the online help and support articles to my best ability

  mainly How to setup S2S IPSEC VPN and Troubleshooting VPN Tunnel articles

 

I can activate and connect the VPN

I can ping a PC on the branch office for around 10 pings +/- if I ping right away.

After that pings time out

Phase 2 Branch Office settings

Thank-you in advance

    Hi Jake,


    did you check the PFS / DH Settings ?


    On Sophos i can see

    Phase1: 2 / Phase2: None


    On the netgear:

    Phase 1: can not see the image / Phase2: 1

    Hi Max,

     

    On the Netgear you have to check the box to the left to have the PFS in play

    The PFS Key Group "Group 1 (768 Bit)" is the setting that would be in play if the box were checked

    I checked my settings on the working Watchguard box.

    The PFS checkbox is not checked there.

     

    I appreciate the suggestion though.

     

    To see the images you have to save the pictures to your PC and open them with a viewer.

    The images are very clear before I upload them

    I must not be doing something right with the blog software for inserting pictures

    Although have trouble seeing pictures in other user posts too.

    I was wrong about saving pictures for better view

    Don't know why the .png files get so poor when uploading

     

    Try these jpg versions

    Now we can see the images. Key Life time is wrong or not ?

     

    Sophos Phase 1: 28800 / Phase2: 3600

    Netgear Phase 1: 86400 / Phase2: 28800

    I played around with the key life time with no success but I will try again and make sure they match

    I can only fire up the Sophos after 5 and on weekend

     

    My "guess" at what the key life means is:

    the key life time was just when a rekey would occur and that they don't have to match

    When the key life ended on either end a rekey would occur

     

    Can you help me better understand the use of the key life for phase 1 and phase 2?

    Thanks Max,

     

     Changing the key life to match on the phase 2 did the trick

    I can now ping non stop

    The key life did not have to be the same for phase 1 but I will make them the same to avoid any goofy stuff that might crop up later.

     

    My guess, based on the entries in the 2 logs, is the handshake for phase 2 requires that the key lives match

     

    Thanks again
