Site to Site VPN wont establish

Hi,

We have a sonicwall we are replacing with a Sophos UTM 9 everything is working except the VPN to a vendor.

2015:03:11-18:51:43 utm01-1 pluto[25691]: "S_VPN" #6: ERROR: asynchronous network error report on eth1 for message to 1.1.1.1 port 500, complainant 2.2.2.2 : No route to host [errno 113, origin ICMP type 3 code 1 (not authenticated)]

Can anyone help? Is there anymore info I can get from the UTM to help find the problem

Tks

  • Are you using main mode? agressive mode is not supported by UTM.
    Also is one of the hosts behind a NAT router? If so did you also configure NAT-T?

    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.

  • Are you using main mode? the other end is using Main Mode, where in the UTM can I see this setting?

    Also is one of the hosts behind a NAT router? NAT-T is selected but I dont think they are NAtting because its talking to public addresses, I'm natting on my side
