I have been running it on a ViP211 for an hour and not one freeze on any channels. D-Link 604 router with Slinger in DMZ over cable internet. Running a SLinger on a 4900, 510 and 301.013 with this version and not one freeze.

IKSlingerVersion2.00

-SNIC bug fix for 6000 model and other IRDs;
-most stable software across all IRD platforms;
-recommended upgrade for all testers;

Must upgrade to this version because or tiers will drop in older versions soon.
