Hi,
I have strongSwan running on a raspberry pi that has ipsec connections to
an OpenBSD iked gateway and it is working well. However, clients on the
network behind the pi seem to have issues sending traffic over tunnels
unless I remove my masquerading iptables configuration; specifically, this
one:
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- anywhere anywhere
Without this entry I'm seeing packets sent upstream outside of the tunnel.
In ASCII art, I'm trying to achieve this fairly standard configuration:
+@@@@@@@@@@+
@ Internet @
+@@@@@@@@@@+
|
| 0/0 route
|
wlan1:192.168.31.26 (DHCP assigned)
+----+ +-------+
|swan|~~~~~~~~~~~~~~ipsec tunnel~~~~~~~~|openbsd|
+----+ +-------+
eth0:10.254.223.1/25 em0:100.64.1.92
wlan0:10.254.223.129/25 lan:10.254.255.1/24
When I start strongSwan without any NAT rules, I'm able to ping from clients
behind the pi device (swan: 10.254.223.128/25, etc.) to 10.254.255.1, but
default route traffic gets dropped from the upstream Internet device (as it
is RFC1918 space and filtered).
Are there specific NAT statements that need to be in place as an exception
to the traffic that will be encapsulated by strongSwan and sent to the
remote peer?
Any help is appreciated; thank you very much in advance.
