Yes, I have sucessfully configured Firewall-1 to filter on a token ring.
However this is not a "straight" install and configuration. Sun's phone support may not
be able to help you. Their standard "fix" for token ring and Firewall-1 problems is to
disable source-routing. But, there will be more gotcha's. We have solved this problem
for our clients by obtaining Firewall-1's "new released filter for token rings" ( yes
The new filter was obtained with the help of Sun Customer Services.
IF AT ALL POSSIBLE AVOID THIS CONFIGURATION ( fw-1 & tr ) UNTIL FIREWALL-1's NEXT
RELEASE. However, the early release version has been successful, but the configuration
is minimal ( air-gaps, it is beta ). We will implement be implementing Firewall-1 on
token rings at the next release.
