[Openswan Users] OS 2.1.2rc5: cannot identify ourselves with either end of this connection.

[Anatoly Ershov]

When establishing a direct conn, everything goes right. The problem 
appears when I (172.16.122.188) am sitting behind natting ISP 
(213.251.198.222 is his public IP) and trying to initiate a host-host 
connection to my security gw (212.12.66.230, same OpenSwan 2.1.2rc5 with 
nat-t enabled). On my client side, I can't explain to ipsec who he is:


ipsec whack --name test1 --host 213.251.198.222 --id 'C=RU, ST=Russian 
Federation, O=TTC Ostankino, OU=IPSec, CN=phantom.telecenter.ru' --cert 
/etc/ipsec.d/certs/my --client 172.16.122.188/32 --to --host 
212.12.66.230 --ca 'C=RU, ST=Russian Federation, L=Moscow, O=TTC 
Ostankino, OU=Certificate Authority, CN=TTC Ostankino Root 
CA/emailAddress=ca at ca.telecenter.ru' --encrypt --tunnel --compress 
--rsasig --psk
002   loaded host cert file '/etc/ipsec.d/certs/my' (10612 bytes)
002 added connection description "test1"

===============
Neither local ip (172.16.122.188), nor hostname == CN 
(phantom.telecenter.ru), nor my isp's public ip (213.251.198.222) as a 
value of "myid" would help.


Here is my barf output: http://age.pp.ru/barf.phantom.os2.1.2rc5.bz2
I guess, I should upgrade to the release 2.1.2 version? :-)
