Hello All,
I have a problem with packets going from my network thru the PIX to my vpn endpoint. If the PIX is off the network (just my verizon dsl modem, and a dlink switch using verizon pppoe dialup client) my safenet client connects to my endpoint fine. When the PIX is connected to the network (verizon dsl modem connected to PIX, the safenet client can't connect, I just get a message in the safenet log saying "message not recieved retransmitting".
The PIX information log has an entry stating:

305011:Built dynamic udp translation from inside:192.169.2.10/500 to outside:155.197.11.8:96

302015:Built outbound udp connection 61515 for outside:151.196.142.42/500 (155.197.142.42/500) to inside:192.169.2.10/500 (155.197.11.8/96)

My question why is the ip address of the PIX port 96 instead of 500 for IPSEC? I think this will solve my problem of the client not connecting to my dlink endpoint.
I need to have port 500 open along with protocol 50, and 51.
Does my config allow for this?
Encerything else works fine. I can connect to the PIX with the cisco vpn client, and split tunneling works. I can map drive, and use remote desktop for server maintenance
If I can get this safenet client to connect back with the dlink thru the PIX I will be in NERVANA!!

Any help is greatly appreciated

You must have a static nat for the workstation that need the vpn. So if necessary you need to have more than one public IP for that.
