Hi,
Based on man 5 iked.conf the following should setup technically 4 flows
(reversing and setting active on the corresponding peer):
/etc/iked.conf
ikev2 esp from 192.168.232.128 to 192.168.232.129 psk "HelloWorld"
ikev2 esp from 192.168.1.0/24 to 192.168.72.0/24 peer 192.168.232.129 psk
"HelloWorld"
The site to site flow (2nd rule) works as intended over the encapsulated
interface. However, the 1st rule will not encapsulate the ICMP traffic when
pinging from the opposite peer (peer 192.168.232.129 used below):
# ping 192.168.232.128
PING 192.168.232.128 (192.168.232.128): 56 data bytes
Oct 03 14:21:13.493860 rule 3/(match) block in on em0: 192.168.232.128 >
192.168.232.129: icmp: echo reply
Here is the ipsecctl flows:
# ipsecctl -sa
FLOWS:
flow esp in from 192.168.72.0/24 to 192.168.111.0/24 peer 192.168.232.129
srcid FQDN/hovpn.local dstid FQDN/rovpn.local type use
flow esp out from 192.168.111.0/24 to 192.168.72.0/24 peer 192.168.232.129
srcid FQDN/hovpn.local dstid FQDN/rovpn.local type require
flow esp out from ::/0 to ::/0 type deny
SAD:
esp tunnel from 192.168.232.128 to 192.168.232.129 spi 0x09a48897 auth
hmac-sha2-256 enc aes-256
esp tunnel from 192.168.232.128 to 192.168.232.129 spi 0x55ef5dfe auth
hmac-sha2-256 enc aes-256
esp tunnel from 192.168.232.129 to 192.168.232.128 spi 0x99bd11bb auth
hmac-sha2-256 enc aes-256
esp tunnel from 192.168.232.129 to 192.168.232.128 spi 0xf5e4357a auth
hmac-sha2-256 enc aes-256
*Note: If I don't have the 1st IKED rule, then the SAD looks correct (only
2 lines, not 4 and still works for the above FLOWS).
I'm sort at a loss with this. Now I don't mind if those 192.168.232.x
interfaces are encapsulated at the end of the day as all critical traffic
will go over the internal network flows, though for monitoring, I'd rather
end point gateway tests to remain encapsulated. Any pointers on where to
look will be greatly appreciated, I've been through the man pages and mail
lists many times trying to work out where I am potentially going wrong.
Thanks in advance.
Jason.
