Thank you very Charles, I will modify the RSA key in the config when I
get home. 

In the network.conf I have 

EXTERN_PROTO0="50 0/0"
EXTERN_PROTO1="51 0/0"

and 

EXTERN_UDP_PORTS="0/0_500"

on both sides

so I think I do not have to set firewall=yes, right?

This is *NOT* correct.  The Modulus is *NOT* the public portion of the
key.
The part you want should be the line above this.  When I run ipsec
rsasigkey, I get a commented line (ie: #pubkey=0s12345...).  The very
large
number after "pubkey=" is what you put in the IPSec configuration file.
NOTE:  Earlier versions of FreeS/WAN used hex encoding (0x1234...)
rather
than the more compact "0s" format...both numbers are identical too
FreeS/WAN, they just differ in format (ie the difference between 255 and
0xFF).

You either need [left|right]firewall=yes, or you need to explicitly
allow
UDP port 500 and IP protocol 50/51 traffic to/from the machine at the
other
end of the VPN.
