IPSec Issue

I have a SRX5308 and a FVS318N connected successfully via an IPSec tunnel. From the Monitoring>Diagnostics tab and I can ping the opposite gateway through the tunnel using the LAN address. I can also ping some hosts on each side of the tunnel. My issue is that some host do not respond and all I get is "Ping Failed" in red rather than the usual window showing the 4 packets transmitted and 100% packet loss or the successful ping response as the case may be. I have verified that the hosts all are set to respond to ICMP requests. The net result is I am not able to access these clients either via http, rdp etc.

I would be glad of any suggestions as to why this may be happening.

  • Check the subnet masks/IP range for each side of your tunnel and make sure they match and also include the range you're trying to access.

    Hi mossdrive,

     

    Welcome to the community! :)

     

    Kindly answer the questions below:

     

    a. Since you are able to get access on some hosts via the VPN tunnel, are there any software firewall/s or anti-virus installed on the hosts that you can't access via the VPN tunnel?  If yes, kindly try to disable or uninstall it then check if same problem occurs.

     

    b. What is the current firmware version of both SRX5308 and FVS318N?
     
    c. Is the time and date synchronized on both SRX5308 and FVS318N as well as the hosts connected in each network? 

     

    I look forward to your response.  

     

     

    Regards,

(There are no software firewalls on the network and the issue remians when the AV is disabled)

       

      b. What is the current firmware version of both SRX5308 and FVS318N? ( v4.3.3-6 on both)
       
      c. Is the time and date synchronized on both SRX5308 and FVS318N as well as the hosts connected in each network? (All are using the same global NTP server)

       

      I look forward to your response.
