One easy way to check if firewalls are blocking remote access is
disabling both and trying to ping again.

I guess that a single firewall would do, depending on how internet is
accessed and the physical layout of the local net.

I don't believe that Samba can be responsible for this pinging trouble.

The command "sshfs" is useful to mount remote folders in a linux
environment. You should check "man sshfs".

example:

Mount

   sshfs   -o   idmap=user   -C   (remote user)@(ip adress):(remote
folder)   (empty local folder)

   sshfs   -o   idmap=user   -C   bill at 192.168.0.99:/home/bill/
/home/bill/remote

Unmount:

   fusermount -u /home/bill/remote
