Hello
I have been a bit remiss, and have not updated my system in a couple of months.
I have been following current for a year or two, in general, without incident.
Anyway, after updating last night, I am unable to establish a ikev2 vpn with an
ios 10.3.2 device. A OBSD6.1<->OBSD6.1 ikev2 vpn is working fine.
I am hoping that someone could shove me in a direction.
I have been using iked with iOS for about a year without a problem.
However, after the update, I noticed that all iOS vpn attempts were failing.
Running # iked -dvvv and trying to connect showed:
...

I found a suggestion that placing an RSA public certificate on the local OBSD
machine could help.
So, I used:
# openssl rsa -in private.key -pubout >
/etc/iked/pubkeys/fqdn/ios.ikev2.myfqdn.com
Now, running # iked -dvvv shows:

sa_state: VALID -> ESTABLISHED from xxx.yyy.1.254:52833 to xxx.yyy.1.20:4500
policy 'ios_vpn'
And, if I run as a daemon, I can see:
# ipsecctl -s all
FLOWS:
flow esp in from xxx.yyy.15.0/24 to 0.0.0.0/0 peer xxx.yyy.1.254 srcid

FQDN/ikesync.myfqdn.com dstid FQDN/ios.ikev2.myfqdn.com type require
SAD:
esp tunnel from xxx.yyy.1.20 to xxx.yyy.1.254 spi 0x05b906be auth hmac-sha2-256
enc aes-256
esp tunnel from xxx.yyy.1.254 to xxx.yyy.1.20 spi 0xebe5b208 auth hmac-sha2-256
enc aes-256
So, according to my OBSD 6.1 the VPN tunnel is up.
But, my iphone does not indicate that a VPN tunnel exists, and it is clearly
unable to access resources that require the VPN connection to be established.
The iphone simply shows "VPN connecting" for a second, and then stops and
reverts to its default status with no VPN.
I think I can get the logs off the iphone if necessary, but that's a bit more
difficult.
I am wondering if there is anything obvious that I am missing.
I am at a loss as to why this was working before the update to current, and why
OBSD shows a "VALID -> ESTABLISHED" state for the tunnel when the iOS device
shows no tunnel has been established.
Thanks for any help.
