SUBJECT. How can I specify 2 different IPs for ppp* interfaces if ipsec and l2tp are installed and configured on the server?
Now they are assigned an IP from the config: xl2tpd.conf but 1 IP is indicated there.
In the /etc/ppp/ip-up script, you can see how the interface is raised: but it is not clear how to specify two IPs for it.
route add -net ${net}0 netmask 255.255.255.0 gw $5

Probably not, it's Point-to-Point. You can only configure routing.
