[strongSwan] multiple right subnets - road warrior config

[Arun G Nair]

Hi,

   I'm trying to connect to a Fortigate vpn gateway with Strongswan
5.0.2 from linux. I've used parameters from windows fortinet ipsec
client (config below) and I'm able to successfully connect to the
gateway. But I can't connect to multiple remote subnets at the same
time. I can only connect to the last subnet defined. If I re-order the
definitions, I can connect to the other subnet. I've done this before
with site to site vpn connections but this is a road warrior set up.
What am I missing here ?


PS:   I've not tried connecting to network-mgmt. That was in the docs
provided for fortinet on windows, but I don't have any servers in that
subnet.
