|    Accessing FVM318 from behind NAT    |
|    21 Jun 04 07:44:48    |
      From: leupi@comcast.net              I have set up a VPN using a Netgear FVM318 and the Netgear Prosafe VPN       client. When I use a dial up connection on the client I can access the       network via the VPN. In order to access anything on the network via computer       name or mapped drive I had to add an entry to the host file on the client       machine (matching an IP to a computer name). Not the ideal way to do it but       it works.              My real problem seems to be when the client is behind a NAT router. I can       establish a VPN connection; hower, I can not ping or access anything on the       network. I looked in the client logs and have this:               6-21: 07:29:59.668        6-21: 07:29:59.668 My Connections\FVS318 - Attempting to resolve Hostname       (seafarer.dnsalias.net)        6-21: 07:29:59.698 My Connections\FVS318 - Initiating IKE Phase 1       (Hostname=seafarer.dnsalias.net) (IP ADDR=68.52.170.145)        6-21: 07:30:00.720 My Connections\FVS318 - SENDING>>>> ISAKMP OAK AG (SA,       KE, NON, ID, VID 5x)        6-21: 07:30:03.724 My Connections\FVS318 - RECEIVED<<< ISAKMP OAK AG (SA,       KE, NON, ID, HASH)        6-21: 07:30:05.146 My Connections\FVS318 - SENDING>>>> ISAKMP OAK AG       *(HASH, NOTIFY:STATUS_INITIAL_CONTACT)        6-21: 07:30:05.146 My Connections\FVS318 - Established IKE SA        6-21: 07:30:05.146 MY COOKIE e8 af 92 9c 3c 18 fa d9        6-21: 07:30:05.146 HIS COOKIE 4d fa a7 5e 53 3a be 4f        6-21: 07:30:06.808 My Connections\FVS318 - Initiating IKE Phase 2 with       Client IDs (message id: 557690FC)        6-21: 07:30:06.808 Initiator = IP ADDR=192.168.1.7, prot = 0 port = 0        6-21: 07:30:06.808 Responder = IP SUBNET/MASK=192.168.0.0/255.255.255.0,       prot = 0 port = 0        6-21: 07:30:06.808 My Connections\FVS318 - SENDING>>>> ISAKMP OAK QM       *(HASH, SA, NON, KE, ID 2x)        6-21: 07:30:09.883 My Connections\FVS318 - RECEIVED<<< ISAKMP OAK QM       *(HASH, SA, NON, KE, ID 2x)        6-21: 07:30:09.883 My Connections\FVS318 - Filter entry 4: SECURE       192.168.001.007&255.255.255.255 192.168.000.000&255.255.255.000       DNS.DNS.DNS.DNS added.        6-21: 07:30:09.883 My Connections\FVS318 - SENDING>>>> ISAKMP OAK QM       *(HASH)        6-21: 07:30:10.033 My Connections\FVS318 - Loading IPSec SA (Message ID =       557690FC OUTBOUND SPI = E3248B65 INBOUND SPI = 214CFDC0)        6-21: 07:30:10.033        6-21: 07:30:44.493 Inbound packet failed validation: 192.168.0.103 ->       66.15.92.28        6-21: 07:30:51.943 Inbound packet failed validation: 192.168.0.103 ->       66.15.92.28              I am a bit confused by the last two lines regarding the 'failed validation'.       They seem to come at random, the only IP I tried to ping before that message       was 192.168.0.1 (the router). Sometimes I will get a 'failed validation'       regarding another computer on my network; but again, it seems to be at       random. The subnet that the client is on is 192.168.1.0 and the VPN is on       192.168.0.0.              Any ideas are appreciated, thanks.              Todd              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
