We are currently running a version of FreeS/WAN 1.95, and have successfully created a tunnel from one network to another.
Once the tunnel has been created, attempts at connecting machines on both private sides fail.
The eth1 interface is receiving ESP packets, and I was expecting it to pass these packets onto the IPSEC interface (?).
We have noticed that the IPSEC0 interface is not receiving or transmitting any packets.
Is there any way of checking whether these packets are getting pushed out onto the IPSEC0 interface??
Also, on starting the ipsec service we get the following
ipsec_setup: WARNING: ipsec0 has route filtering turned on, KLIPS may not work
ipsec_setup: (/proc/sys/net/ipv4/conf/ipsec0/rp_filter = `2', should be 0)
ipsec_setup: WARNING: eth1 has route filtering turned on, KLIPS may not work
ipsec_setup: (/proc/sys/net/ipv4/conf/eth1/rp_filter = `1', should be 0)
ipsec_setup: ...FreeS/WAN IPsec started
is this possibly causing the route to IPSEC0 to fail???
I have tried changing the rp_filter values.....but they get changed automatically by something else soon after.
Any help would be appreciated.
Andrew.
