[nsp] IPSec between cisco and D-Link DI-804V?

[Mart Norman]

Hello,

Is anybody successfully running ipsec between Cisco and D-Link DI-804V?
i'm having a problem with this.


10.1.1.0/24 -- cisco -- internet -- di-804v -- 10.1.2.0/24
		1.1.1.1		  2.2.2.2

If i replace either of them with FreeBSD box running racoon for isakmp,
everything works fine

Cisco:

crypto isakmp policy 1
 encr 3des
 hash md5
 authentication pre-share
 group 2
crypto isakmp key plapla address 2.2.2.2
!
!
crypto ipsec transform-set mart esp-3des esp-md5-hmac
!
!
!
!
crypto map staticmart 10 ipsec-isakmp
 set peer 2.2.2.2
 set transform-set mart
 set pfs group1
 match address 108

[..]

interface Serial2/0
 ip address 1.1.1.1 255.255.255.0
 crypto map staticmart

[..]
ip route 10.1.2.0 255.255.255.0 Serial2/0
[..]
access-list 108 permit ip 10.1.1.0 0.0.0.255 10.1.2.0 0.0.0.255


I tracked the problem down to the point where cisco sends ID Payload
which appears to be different than DI-804V expects and this causes
negotiations to fail.

Any hints how to overcome it? Or i just have to accept that cisco's and
D-Link's implementations of ipsec are not compatible?
