Hello List,
I use stongswan on 3 WRT Routers (TP-Link Archer C7) with 2x OpenWRT
15.05.1 and one new with LEDE 17.01.0.
OpenWRT use strongSwan 5.3.3, Linux 3.18.23, mips
LEDE use strongSwan 5.5.1, Linux 4.4.50, mips
Okay, I want to build a routed VPN connection between 2 locations. The
conn1 (192.168.0.0/24) is the main location with static public ip
address. The conn2 (192.168.1.0/24) has currently a dynamic public ip
address (DSL connection), but will be replaced with the new LEDE Router
with a LTE connection, which has no public IP address. For testing I
made a new subnet (192.168.2.0/24) and a new connection (conn2new).
conn1- 192.168.0.0/24 - lanip 192.168.0.254 - wanip fixed private (full
port forwarding from wan ip)
conn2 - 192.168.1.0/24 - lanip 192.168.1.254 - wanip dynamic
conn2new - 192.168.2.0/24 - lanip 192.168.2.254 - wanip private (no port
forwarding from wan ip possible)
My Problem is now, that I cannot ping from the router at 192.168.0.0/24
to the hosts behind the router from subnet 192.168.2.0/24 - But I can
reach the vpn-router.
Works:
ping from 192.168.0.254 -> 192.168.2.254
Don't Work:
ping from 192.168.0.254 -> 192.168.2.102 (example - host firewall is
open for icmp, and ping from local router to the host works)
The statusall command also don't show me, that the subnet is routed. And
when I try to "route" it I get this:
ipsec route conn2new
routing 'conn2new' failed
I am not sure if it is a problem of the right=%any or if it is a bug
from LEDE. Hope somebody can give me a hint.
Thomas
