Hi I'm running Barrier Breaker version of OpenWRT and I have setup a VPN according to: http://wiki.openwrt.org/inbox/strongswan.howto I can connect to the VPN with my iPhone or Mac (to 10.10.1.0/24 network). I can also connect from Windows 7. An IP is allocated to the client successfully using DHCP. Once connected I can't access anything on the network. /etc/firewall.user contains:
# This file is interpreted as shell script.
# Put your custom iptables rules here, they will
# be executed with each firewall (re-)start.
iptables -I INPUT -m policy --dir in --pol ipsec --proto esp -j ACCEPT
iptables -I FORWARD -m policy --dir in --pol ipsec --proto esp -j ACCEPT
iptables -I FORWARD -m policy --dir out --pol ipsec --proto esp -j ACCEPT
iptables -I OUTPUT -m policy --dir out --pol ipsec --proto esp -j ACCEPT
# Enable ssh and HTTP to router
iptables -I INPUT 1 -p tcp --dport 22 -j ACCEPT
iptables -I OUTPUT 1 -p tcp --sport 22 -j ACCEPT
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
iptables -I OUTPUT 1 -p tcp --sport 80 -j ACCEPT
/etc/ipsec.conf contains:
# ipsec.conf - strongSwan IPsec configuration file

(The real domain name of the router has been replaced above with xxx.yyy.com).
/etc/strongswan.conf contains:
# strongswan.conf - strongSwan configuration file
charon {
dns1 = 10.10.1.1
# number of worker threads in charon
threads = 16
# send strongswan vendor ID?
# send_vendor_id = yes
plugins {
dhcp {
server = 10.10.1.1
}
sql {
# loglevel to log into sql database
loglevel = -1
# URI to the database
# database = sqlite:///path/to/file.db
# database = mysql://user:password@localhost/database
}
}
# ...
}
pluto {
}
libstrongswan {
# set to no, the DH exponent size is optimized
# dh_exponent_ansi_x9_42 = no
}
When I connect with both Windows 7 and also iPhone ipsec status on router shows:
Security Associations (2 up, 0 connecting):
ios[5]: ESTABLISHED 4 seconds ago, xxx.xxx.xxx.xxx[C=AU, O=Netroworx, CN=xxx.xxx.com]...xxx.xxx.xxx.xxx[C=AU, O=Netroworx, CN=client]

win7{4}: 0.0.0.0/0 === 10.10.1.0/24
(Sensitive ips and domain names replaced with xxx)
Any ideas on why packets are not being routed over the vpn?
Could this be a NAT thing?
Update: I get the following when trying to install strongswan on Barrier Breaker:
opkg install strongswan-full
