Hi,

I am having trouble setting up a connection to a provider (and am also
running into delays getting logs from them) so I was wondering if anyone
can spot a glaring error or point me in the possible right direction as to
why my tunnel isnt coming up.

First off - the connection details (as provided by the remote party):
*Remote:*
Remote Device: Huawei VRP
Auth Method: Pre-Shared Key
Encryption: IKE
IKE PFS: 3DES
IKE Encryption Algorithm: SHA1
IKE Hashing Algorithm: Group 2 (1024)
IKE SA Lifetime: 14400
Transform (IPSec Protocol): IKE
IPSEC Perfect Forward Secrecy: ESP
IPSEC Encryption Algorithm: 3DES
IPSEC Hashing Algorithm: SHA1
IPSEC SA Lifetime: 3600
Hosts: 172.25.48.43, 172.25.48.36

Here is my config:
*[root at server ~]# cat /etc/ipsec.conf*
# /etc/ipsec.conf - Openswan IPsec configuration file
version 2.0 # conforms to second version of ipsec.conf specification

# basic configuration

uniqueids=yes
include /etc/ipsec.d/*.conf

*[root at server ~]# cat /etc/ipsec.d/host-prd.conf*

Any ideas would be very welcome! Apologies if i'm missing something silly -
i think i cant see the wood for the trees at the moment!
