Estou tentando configurar uma VPN IPSec em um Fortigate 80C e conectá-lo usando o Shrew Soft VPN. Estou com uma falha de negociação, mesmo que a depuração na unidade Fortigate mostre os mesmos valores para ambas as propostas, exceto para o ID da proposta:

Alguma idéia do porquê isso está acontecendo?

Aqui está a configuração do túnel: 

BKFGT80C-03 # show vpn ipsec phase1-interface BKIPSECVPN 
config vpn ipsec phase1-interface
    edit "BKIPSECVPN"
        set type dynamic
        set interface "WANProsodieDATA"
        set mode aggressive
        set xauthtype pap
        set proposal 3des-sha1 aes128-sha1
        set authusrgrp "vpn-users@SRV3"
        set psksecret ENC nhHJbl/trs/6Fxx383T9wTSrI85maR2cvP2R4N5XD0VyLc/rdzp/QnWFKOEYlXEIBc6ViKqSrb2GCliq5+4y3dxuRG3hurRq5T4Vz1uYf23y/+qE8xMspKvWOJkb2BP8wV7bkNgd7TjJabL/GfOU6pIsuga9J0kknxTdEPl8fWzj3U4g85R9+BO7264YQ/7ZopFZHA==
        set keepalive 15
    next
end

BKFGT80C-03 # show vpn ipsec phase2-interface BKIPSECVPN_Ph2 
config vpn ipsec phase2-interface
    edit "BKIPSECVPN_Ph2"
        set keepalive enable
        set phase1name "BKIPSECVPN"
        set proposal 3des-sha1 aes128-sha1
    next
end

Você poderia colar a configuração fortigate do túnel? (vai editar com uma resposta mas sem a configuração eu não posso te ajudar)

Você também pode incluir a configuração do Shrew Soft? Claramente há um erro de correspondência na configuração. ID local? Grupos DH? O que acontece se você desmarcar XAUTH e usar PSK?

Eu posso ver na sua configuração que você tem diferentes tipos de cifra para a fase 2: 

set proposal 3des-sha1 aes128-sha1

e para a Shrewsoft VPN 

s:phase2-transform:esp-3des
s:phase2-hmac:sha1

Pur AES-128 ou 3DES. Isso deve resolver o problema.
