XG to UTM9 Site to site IPSEC vpn can ping one direction only

JDaus

Hi All,

First time poster, so if i got this in the wrong location, sorry.

I have been using UTM since astaro days and not much i can't do with it.

I have only been using the XG firewall for a few days now, so its a learning curve.

 

Now to my problem, i can ping from the local lan on the XG FW to the UTM but not back the other way.

I have spent all day today researching and trialinig various things, but am stuck.

I have followed the below tutorial and configured only 1 network on each side

I have also looked at the following for potential inspiration:

https://community.sophos.com/products/xg-firewall/f/vpn/75359/ipsec-site-to-site-vpn---ping-one-way-but-not-other

and many more.

 

I tried to follow the original link above as closlely as possible, obviously changing IPs to suite my config, and have even tried tweeking firewall rules and watching firewall logs on both systems, nothing is pointing me in the right direction. has anyone successfully follwed the above guide or am i better off just upgrading the UTM to a XG right away (wanted to make it my remote site once i got a basic understanding of the config of XG.

    Have you tried to ping after enabling ping for the VPN zone under 'Administration -> Device Access -> Local Service ACL'?

    Since the ping in the other direction works i assume that the tunnel as such is working.

    This was the problem ... at least i think it was, when i tried to connect to rdp this morning from UTM to xg it worked, then i tried to ping back from XG lan to UTM lan and that worked. unfortunately i had enabled the ping acl before trying this, so i am not sure if that one change fixed everything or not ... looks like i have more reading to to on the XG now ...

     

    Thanks DNA for the response, much appreciated.

    Unfortunately this was not the problem, it has allowed me to ping to the firewall, but all other communications from UTM lan to XG lan are not working, so it looks like im probably doing something wrong in the firewall settings. time to trash those settings and re setup i think.
