You do realize that using a phase2 timeout of 1000000 will allow SA's to 
exist for over 11 days? A typical IPsec SA only lives for an hour or so. 
Even a typical ISAKMP SA only lives for 8 to 24 hours. In any case, I 
suppose you could manually edit the phase2-life-secs value in the 
registry or a file depending on the platform you use. On Windows, the 
value is stored under ...

HKEY_CURRENT_USER\Software\ShrewSoft\vpn\site\[site name]

... and on Linux/BSD/OSX its stored in the file ...

~/.ike/sites/[site name]
