Hi nkirkby,

For firewalls, you would need to open the complete ephemeral port range (TCP only) for our solvers.
You can obtain the starting port and range with the following commands:
   Linux:  cat /proc/sys/net/ipv4/ip_local_port_range 
   Windows: NetSh INT IPV4 Show DynamicPort TCP

Also, you would want TCP 32958 for ansoftrsmservice and whatever ports your selected MPI uses.

"Determining memory availability"  is MPI related settings and most likely not firewalls.

Some MPI related items to look when solving on remote Linux solves are:
- using IMPI 2021 in RHEL8.x OS variants 
- Passwordless SSH 
- Environments to use the correct network (if multiple networks are available on each machine)
- specifying the user/password in AEDT-Tools-Options-General Options-Remote Analysis

Some MPI related items to look when solving on remote Windows solves are:
- installing the correct Intel MPI version, creating the service
- registering the user password on each machine
- Environments to use the correct network (if multiple networks are available on each machine)
- specifying the user/password in AEDT-Tools-Options-General Options-Remote Analysis
