i have a machine with a normal ethernet interface on which
all packets of the machine itself pass out (here: fxp0),
as well as a tun0 (openvpn interface) and a ppp0 (another

now what i'd like to do is to make all traffic that arrives from
the openvpn tunnel -from various clients- at tun0 pass out
to the other tunnel ppp0.

openvpn uses 10.192/16 net.

my NAT config is

map ppp0 -> 0/32 portmap tcp/udp 30000:60000
map ppp0 -> 0/32

if i manually add a destination IP with "route add", this works
fine for the particular IP.

the machine has a default gateway set for the traffic generated
by itself and i cannot chang it to be the ppp0 ip.

now what to do here?
