multiple if_ipsec

[Victor Gamov]

Hi All

I have FreeBSD box (11.1-STABLE FreeBSD 11.1-STABLE #0 r327786) and 
simple configuration with two if_ipsec configured like
=====
ipsec25: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1400
	description: -so: Sofy
	tunnel inet IP-FreeBSD --> IP-Cisco-RTR-1
	inet 10.10.98.6 --> 10.10.98.5  netmask 0xfffffffc
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
	reqid: 25
	groups: ipsec
ipsec30: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1400
	description: -so: Kurskaya
	tunnel inet IP-FreeBSD --> IP-Cisco-RTR-2
	inet 10.10.98.1 --> 10.10.98.2  netmask 0xfffffffc
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
	reqid: 30
	groups: ipsec
=====


IPsec started with "flush; spdflush;" only config.  FreeBSD setkey -DP 
reports (IPv6 skipped)
=====
0.0.0.0/0[any] 0.0.0.0/0[any] any
	in ipsec
	esp/tunnel/IP_Cisco_RTR_1-IP_FreeBSD/unique:25
	spid=9 seq=7 pid=94296 scope=ifnet ifname=ipsec25
	refcnt=1
0.0.0.0/0[any] 0.0.0.0/0[any] any
	in ipsec
	esp/tunnel/IP_Cisco_RTR_2-IP_FreeBSD/unique:30
	spid=13 seq=5 pid=94296 scope=ifnet ifname=ipsec30
	refcnt=1
0.0.0.0/0[any] 0.0.0.0/0[any] any
	out ipsec
	esp/tunnel/IP_FreeBSD-IP_Cisco_RTR_1-IP/unique:25
	spid=10 seq=3 pid=94296 scope=ifnet ifname=ipsec25
	refcnt=1
0.0.0.0/0[any] 0.0.0.0/0[any] any
	out ipsec
	esp/tunnel/IP_FreeBSD-IP_Cisco_RTR_2-IP/unique:30
	spid=14 seq=1 pid=94296 scope=ifnet ifname=ipsec30
	refcnt=1
=====

Then racoon.conf (from security/ipsec-tools-0.8.2_2) configured like
=====
remote "kur" {
   exchange_mode main;
   doi ipsec_doi;
   situation identity_only;

   my_identifier address IP-FreeBSD;
   peers_identifier address IP-Cisco-RTR-2;
   verify_identifier on;

   nonce_size 16;
   lifetime time 240 min;   # sec,min,hour
   initial_contact on;
   #        support_mip6 on;
   support_proxy on;
   proposal_check obey;    # obey, strict or claim

   proposal {
     encryption_algorithm 3des;
     hash_algorithm sha1;
     authentication_method pre_shared_key ;
     dh_group 2 ;
   }
}
remote "sofy" {
   exchange_mode main;
   doi ipsec_doi;
   situation identity_only;

   my_identifier address IP-FreeBSD;
   peers_identifier address IP-Cisco-RTR-1;
   verify_identifier on;

   nonce_size 16;
   lifetime time 240 min;   # sec,min,hour
   initial_contact on;
   #        support_mip6 on;
   support_proxy on;
   proposal_check obey;    # obey, strict or claim

   proposal {
     encryption_algorithm 3des;
     hash_algorithm sha1;
     authentication_method pre_shared_key ;
     dh_group 2 ;
   }
}

sainfo anonymous {
   pfs_group 2;
   lifetime time 24 hour;
   encryption_algorithm		aes;
   authentication_algorithm	hmac_sha1, hmac_md5;
   compression_algorithm		deflate;
}
=====


All local SA configured and established and remote side (Cisco routers) 
report SA established too.

But traffic goes via only one ipsec-interface.


Can anybody explain where is my problem:
- FreeBSD misconfig
- racoon misconfig
- racoon not support multiple ipsec configuration
- something else


Thanks
