Regarding the issue with display of subnets on the index.cgi page, I 
think I have (in our case) narrowed it down to tunnels with multiple 
subents defined in a comma separated list.

A tunnel with remote subnet "10.7.0.0/24,10.7.1.0/24" displayed on 
index.cgi as "10.7.0.0/3". When changed to "10.7.0.0/23", it displays 
properly on index.cgi.

I suspect that the code to display the subnet pre-dates the change to 
allow multiple subnets in one tunnel and needs to be modified?

I have opened bug 11604 for this issue.

PS: My output below was wrong, the index.cgi page showed 10.253.0.0/3, 
not "10.6.0.0/3". I fixed that in the bug description.
