IPSec VPN with SRX5308
Hi everyone,
I bought recently a SRX5308 firewall. I want to achieve a Client to Gateway IPSec VPN with this device. I used the VPN Wizard to configure the Gateway and I installed the Netgear VPN Prosafe client on a Windows 7 computer. I can open the tunnel but I get two issues :
* When the tunnel is open, I can't go on Internet (DNS fails)
* I can't ping any host in the remote LAN, even the VPN gateway.
I made some tests and I found that the client ping packets reach the LAN host I want to ping, the LAN host send its reply to gateway, but gateway doesn't arrive to send packets to the client.
What should I do to solve my problem ?
Thanks for your help.

- jmizoguchiVirtuosoIPsec tunnel will only uses local internet traffic for http etc
IPsec tunnel will not resolves PC name via tunnel unless you use modeconfig with own DNS server
IPsec needs 2x public and 2x private with BOTH side different LAN subnet (ex, 192.168.50.x and 192.168.60.x) - franck_martin2Aspirant

This means that client http requests cross the VPN tunnel ?IPsec tunnel will not resolves PC name via tunnel unless you use modeconfig with own DNS server
So, I have to use modeconfig if I want to go on Internet while tunnel is open ?IPsec needs 2x public and 2x private with BOTH side different LAN subnet (ex, 192.168.50.x and 192.168.60.x)
It's already done. I also created a static route between the gateway and the client. - jmizoguchiVirtuosoHttp will NOT use IPSec . Local where client is connected
Only SSL-VPN in full tunnel - franck_martin2AspirantIf HTTP doesn't use the IPSec tunnel, why I can't go on Internet when the tunnel is open?
- aditMentorNo static route needed. Post screenshots of what you did.
- franck_martin2AspirantI will explain what I did in the following lines:
I used the "VPN Wizard" to create the VPN configuration. I choosed "VPN Client", I entered a name and a pre-shared key for the connection, a FQDN for the remote host and the gateway. I clicked on "Apply".
Then, I installed Netgear Prosafe VPN client on a Windows 7 computer. I entered the gateway's public IP, the pre-shared key and the two FQDN in the reserved fields.
Then, I entered an IP address which is in the remote LAN IP address range for the client, the network LAN address and mask. I used the gateway address for the DNS server field.
I created a static route on the gateway which destination is the client, a static route on a computer of the remote LAN which destination is the client and two static routes on the clients which go to the gateway and to the remote LAN host. - franck_martin2AspirantI will explain what I did in the following lines:
1. I created the VPN policy with the VPN Wizard:I clicked on "VPN Client".I entered a connection name and a pre-shared key.I entered two FQDN for remote client and gateway.I clicked on "Apply".
2. I installed on a Windows 7 PC the Netgear Prosafe VPN client.
3. I clicked on "Configuration" and "Configuration assistant".
4. I answered all questions on the assistant.
5. On the Netgear client:I entered an IP address for the client which is included in the remote LAN IP address range.I entered the remote LAN IP address and mask.I entered the gateway IP address for the DNS field.
6. I created some static routes between the gateway and the client and between an host in the remote LAN and the client. - jmizoguchiVirtuoso

IPsec tunnel will NOT allow any internet traffic to go through your VPN tunnel f for remote user. It will continue to use local internet for surfing while other sharing file can be used in the tunnel - jmizoguchiVirtuoso

This setup ONLY allows to access server, shared files etc while you will NOT have any internet taffic to surf via SRX while remote user is connected. It will use local internet where user is connected for surfing the internet
if you want ALL traffic go ONLY via tunnel including internet (surfing for user) then you need to use SSL-VPN tunnel (no IPsec) with full tunnel (no split tunnel) - franck_martin2AspirantWhy my gateway (SRX5308) can't transfers ping packets from LAN host to client ?
