firewall

Currently we have a Linux-based firewall which NAT-ing our public IP address to give internet access to our staff's PCs and a Windows Server 2003 for internal filesharing.

I want to host Redmine/SVN (a bugtracker) internally behind this firewall using a Linux server. This webserver will be accessed by our clients externally so they can post bug reports. This means that I have to open port 80 & 22 at the firewall to give access to the webserver and me to SSH it from home.

However, let's say I'm using password-based SSH for the webserver and somebody cracked it. Does that mean the cracker could ping and access other servers and PCs in the network?
