Fortigate Remote VPN : no matching gateway for new request

  • 772

I am trying to configure a Fortigate 60C to act as an IPSec endpoint for remote VPN.

I configured it like this :

SCR-F0-FGT100C-1 # diagnose vpn ike config

vd: root/0
name: SCR-REMOTEVPN
serial: 7
version: 1
type: dynamic
mode: aggressive
dpd: enable  retry-count 3  interval 5000ms
auth: psk
dhgrp:  2
xauth: server-auto
xauth-group: VPN-group
interface: wan1
distance: 1
priority: 0
phase2s:
  SCR-REMOTEVPN-PH2 proto 0 src 0.0.0.0/0.0.0.0:0 dst 0.0.0.0/0.0.0.0:0  dhgrp 5  replay  keep-alive  dhcp
policies: none

Here is the configuration: 

config vpn ipsec phase1-interface
    edit "SCR-REMOTEVPN"
        set type dynamic
        set interface "wan1"
        set dhgrp 2
        set xauthtype auto
        set mode aggressive
        set proposal aes256-sha1 aes256-md5
        set authusrgrp "VPN-group"
        set psksecret ENC xxx
    next


config vpn ipsec phase2-interface
    edit "SCR-REMOTEVPN-PH2"
        set keepalive enable
        set phase1name "SCR-REMOTEVPN"
        set proposal aes256-sha1 aes256-md5
        set dhcp-ipsec enable
    next
end

But when I try to connect from a remote device (I tested with an Android Phone), the phone fail to connect and the fortinet return this error :

2012-07-20 13:08:51 log_id=0101037124 
type=event 
subtype=ipsec 
pri=error 
vd="root" 
msg="IPsec phase 1 error" 
action="negotiate" 
rem_ip=xxx
loc_ip=xxx 
rem_port=1049 
loc_port=500 
out_intf="wan1" 
cookies="xxx" 
user="N/A" 
group="N/A" 
xauth_user="N/A" 
xauth_group="N/A" 
vpn_tunnel="N/A" 
status=negotiate_error error_reason=no matching gateway for new request 
peer_notif=INITIAL-CONTACT

I tried searching on the web, but i did not find anything revelant to this.

Do you have any idea of what can be the problem ? I tried many combinaisons of settings on the fortigate without success..

  1. Try this:

    Example DHCP server configuration

    config system dhcp server
  edit 3
    set dns-service default
    set default-gateway 192.168.100.254
    set netmask 255.255.255.0
    set interface "SCR-REMOTEVPN"
      config ip-range
        edit 1
          set start-ip 192.168.100.100
          set end-ip 192.168.100.199
        next
      end
    set timezone-option default
    set server-type ipsec
      config reserved-address
        edit 1
          set ip 192.168.100.200
          set mac 11:22:33:44:55:66
        next
      end
  next
end

    Define phase 1 with Mode Config disabled

    config vpn ipsec phase1-interface
  edit "SCR-REMOTEVPN"
    set type dynamic
    set interface "wan1"
    set ip-version 4
    set ike-version 1
    set local-gw 0.0.0.0
    set nattraversal enable
    set keylife 86400
    set authmethod psk
    set mode aggressive
    set peertype any
    set mode-cfg disable
    set proposal aes256-sha1 aes256-md5
    set add-route enable
    set localid ''
    set localid-type auto
    set negotiate-timeout 30
    set fragmentation enable
    set dpd enable
    set forticlient-enforcement enable
    set comments "based on fortinet kb (FD37351)"
    set npu-offload enable
    set dhgrp 2
    set wizard-type custom
    set xauthtype auto
    set authusrgrp "VPN-group"
    set default-gw 0.0.0.0
    set default-gw-priority 0
    set psksecret ENC
    set keepalive 10
    set distance 15
    set priority 0
    set dpd-retrycount 3
    set dpd-retryinterval 5
    set xauthexpire on-disconnect
  next
end

    enable DHCP over IPsec in the VPN phase 2.

    config vpn ipsec phase2-interface
  edit "SCR-REMOTEVPN"
    set phase1name "SCR-REMOTEVPN"
    set comments "based on fortinet kb (FD37351)"
    set dhcp-ipsec enable
  next
end
