ERP access over site-to-site VPN tunnel

We just acquired a new company in another state and they are not yet part of our domain. As a temporary measure I created a tunnel between their network and ours so our HR dept can access their ERP server via the client to do payroll. (We are both using Sonicwalls) The tunnel works and I can ping the ERP sever from one of our HR laptops located in my local network but the ERP client can’t connect. We also set up a new server there to start building a new infrastructure for future migration. I can RDP into that and even into some their existing servers, but we can’t connect to any databases using SQL Mgmt Studio. Those are just the things we’ve had time to try

I realize there are a lot of factors involved and without actually seeing the firewall setups it may be impossible to help much. Their firewall is kind of a mess, lots of customization, old configurations left over from companies they used to be a part of but no longer exist. It seems like it’s something preventing access to databases specifically and I’m hoping for some suggestions of things to check.

Edit: ERP System is JobBoss
