I hate to beat a dead horse but there are 2 things wrong here. First,
ip_forwarding is not a valid options tag for the SunOS kernel config
file. Second, the config program will reject the -1 as asyntax error
(see bug 1047296).

The correct line for the kernel config file is this:

options IPFORWARDING=0xffffffff


To affect this change for _all_ kernels built, modify the file,
/sys/`arch -k`/netinet/in_proto.c:

#define IPFORWARDING 0xffffffff
