Hi,
Which mode you use ? Xauth ? ModeConfig ?
Because there is a "known issue" with NETGEAR Router and ModeConfig
without XAUTH

I'm aware of this and have both xauth and modeconfig setup. (See second
sentence below). As I also mentioned I can successfully connect to two
other netgear vpn routers. It is just the SRX5308 that I can't. I've
got all three devices setup identically and I just change the connect to
address in the shrew client.

Problem:
I'm trying to establish a IPSec VPN to a Netgear SRX5308 with the
Shrew Soft VPN Client. I've got it configured correctly to do mode
config and xauth. If I point the exact same configuration at my
Netgear FVX538 or Netgear FVS336G (also setup the same as the
SRX5308) it connects just fine. However on the SRX5308 I get a
"invalid message from gateway" message on the VPN client. I've
tried using the 3.0.6-9.1 firmware as well as the beta 3.0.7-11.1
firmware. They both behave the same way.
VPN Client Version = 2.1.7 and 2.2.0-alpha10
Windows OS Version = Windows 7 Ultimate (32-bit and 64-bit)
Gateway Make/Model = Netgear SRX5308 (broken)
Gateway OS Version = 3.0.6-9.1 and 3.0.7-11.1 (beta)
Gateway Make/Model = Netgear FVX538 and FVS336G (working)
Gateway OS Version = 3.0.6-29
In comparing the IKE decrypted packed dumps between the FVS336G and
the SRX5308 they are the same up to the point of doing the mode
config negotiation. The FVS336G does a ISAKMP_CFG_REQUEST (1) and
receives a ISAKMP_CFG_REPLY (2) with all the data needed (ip, mask,
dns, etc). The SRX5308 does the same ISAKMP_CFG_REQUEST (1) and
receives a ISAKMP_CFG_SET (3) with the needed information (ip, mask,
dns, etc). Because the packet is a SET instead of a REPLY the client
doesn't recognize the packet as one it expects and fails to bring up
the tunnel.
I've got packet captures of both firewalls that I can send if necessary.
