site to site and remote ipsec vpn

Hi Folks,
I have a site to site VPN set up (working fine) using preshared keys.

I'd like to create a new ipsec remote user vpn also using preshared keys however I get this warning when I try to do so:

Site-to-site VPN → IPsec → Connections:
Preshared key conflicts with connection 'siteA'. Continuing will disable that connection.


To me this implies that I can only have 1 ipsec connection (of either type) using preshared keys. If that is the case, should switch one or the other to using certs?

  • OK, I found a bit more info and got it all working:
    if the site to site vpn is set to receive only then all PSKs must match. setting the remote user PSK to the same as the site to site PSK resolved the issue.
  • This was the old solution, Fizzer, but since V7.5 (I think), there's been a checkbox for 'Enable probing of preshared keys' on the 'Advanced' tab of IPsec.

    Cheers - Bob
