In out company we have some Zyxel Zywall firewalls (10, 35, 70).
Now I try to setup a software VPN router with linux for my home
that grant access to the company net.

Which software can/should I use?

After a short internet search I found two canidates:
FreeS/WAN and OpenVPN.

Since kernel 2.6 Linux is IPsec-enabled by default through the import of
the KAME-stack. Just take care, that the appropriate options are
compiled into the kernel or the modules are loaded. If you're running on
2.4.x, FreeS/WAN (or StrongS/WAN) are kernel-patches you need.
AFAIK the ISAKMPd is already ported to Linux, which may be an
alternative. OpenVPN is not compatible with IPsec and therefor unuseable
for the ZyWall.  Maybe you'll give a try on L2TP, but IPsec maybe the
