SOPHOS XG - SSL VPN no access across IPSEC tunnel

Have 2 sites connected with an IPSEC tunnel - head office  (SSL VPN - branch office  (SSL VPN


when a user connects via ssl vpn they can't communication to the other site.  What do i have to add in order to accomplish this?  please be specific I'm a noobie on sophos.  I've seen articles on this, but everything seems to relate to the UTM9 not the XG.

I've tried adding the ssl vpn network in the ipsec connection local sub, and the remote sub on the other side, but still didn't work.
