8 TopicsRemote Client Full Tunnel VPN with SRX5308 and Shrew Soft - Some Websites Don't Load
Hi everyone, I've really been scratching my head on this one. Any help would be greatly appreciated. Remote users need to access remote servers through the office, which is whitelisted for access. Since the remote servers are dynamic IPs (AWS), I'm trying to send all remote traffic through the office while we investiage better solutions. SSL VPN is not an option due to compatibility issues with modern browsers and OSes. I have configured an IPSEC VPN for remote users. It connects, but only some websites load. Others will time out. DNS does not seem to be the issue, as a ping will resolve the IP (and some sites load). I thought it might be related to fragmentation, but my tests (ping with different packet sizes) indicate the MTU should be 1500. Shrew Soft Client --VPN--> Office --Whitelist--> Remote Servers Info VPN policy Local IP: Any Shrew Soft Client: Policy - Obtain Topology Automatically or Tunnel All Testing/Troubleshooting Mode Config Connects, but local traffic only. IP Ranges of Servers I backtracked the ranges the servers could use, but it was the same results as tunneling all (page times out) Netgear VPN client Internet traffic didn't flow when I tried to set the range for the entire Internet (if I remember correctly). L2TP (MSCHAPv2) with built-in Windows 10 client PSK, but blank Computers that have previously been on the internal network behind the SRX5308 will connect. Computers that have not been on the internal network behind the SRX5308 get an error "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer." Error 789 in event logs Certifcate Did some research, but it seemed complicated. Will likely research further. I know I'm close, since some websites do load when connected. I'm leaning towards it still being a fragmentation/MTU issue, but I can only change that in Shrew Soft with using Mode Config. I have not tested changing the MTU on the SRX5308 yet. This is the first time I've attempted a full tunnel this way. I'm open to any suggestions for getting this working, except for PPTP due to security concerns and SSL due to compatibility. Thanks in advance!Solved3KViews0likes2CommentsFVS318N csr signed by Openssl intermediate CA not accepted
Hello all, I have a FVS318N router, frmware 4.3.4-2. I have generated a certificate signing request (CSR) from the firewall (SHA-1 + RSA2048). I have issued certificates: using openssl and my Intermediate CA certificate & PK. The firewal refuses to load this certificate. using openssl and an Root CA certificate. The firewal accepts this certificate. In both cases: no extended key usage SHA1 + RSA2048 both the Root and Intermediate CAs certificates are loaded as trusted CAs in the firewall both the Root and Intermediate CAs certificates are SHA1 + RSA2048 Questions: Are Intermediate CAs issued certificates supported the Netgear CSR? If yes, any tips? The certificate I have uploaded is used now for the administration interface, which is unwanted. I would want to add an IPSEC only certificate which does not interfere with the SSL certificate. What keyUsage/Extended key usage to add or exclude? The documentation refers to IPSEC VPN extKeyUsage (EKU). AFAIK the IPSEC specific EKUs have been deprecated long ago and should no longe be used. The IPSEC VPN OIDs are not mentioned in the Netgear doc, does anyone know what do they mean? Is there any way to grab more information (ie: logs) of what happens inside for certificate management? The firewall has a serial port and I still have a PC with a serail port on. Can it be told to log anything usefull there (or elsewhere)?5.3KViews0likes7CommentsIpsec vpn between srxn3205 doesn't connect.

Hi there! Pull hairs over here, I have a IPSec Tunnel between two pFsense Firewalls. Pings to both Gateways without issue, pings to PCs on Remote LAN succeed without issue. When pinging the ReadyNAS on the Remote Network, half of the pings fail while the other half succeed. At this time, I cannot access the ReadyNAS on the Remote Network from the Main Network over VPN. There is no issue pining the ReadyNAS when on the same local subnet. Local Nework: 192.168.10.x Remote LAN: 192.168.30.x (c) 2015 Microsoft Corporation. All rights reserved.

Tunnel establishes but drops within seconds.
I'm having a rather frustrating issue with connecting to the FVS318N via the Android built-in VPN client. I have verified all the settings are correct on both ends and the tunnel comes up just fine everytime. However, it drops within a matter of 10-20 seconds. I have the same issue when the phone is connected to 3G/4G or WiFi. I have used the Netgear Client as well as Shrewdsoft on Windows machines and they both work ok, after tinkering with the settings/policies. But everything I've tried so far hasn't worked for Android. Have tried a phone and a tablet, just to be sure. Would appreciate any help. Thanks. Details: FVS318N on FW 4.3.3-6 Phone and tablet on Android 5.0.1 LAN Subnet on FVS318N and VPN clients subnet are different (192.168.2.0 and 192.168.4.0) Mode config and non Mod Config both tried, same result. Other settings are just standard, as per VPN Wizard defaults.5.9KViews0likes7CommentsIPSEC Site to Site FVS336 to FVS318
Hi Netgear Community, I want to set up a Site to Site connection between FVS336 and FVS318 at our costumer s office. At there site the FVS318 is behind a firewall. They forward ESP, AH and Port 500 UDP to the device. Is there any possibility to check the ports (like telnet)? Both routers were configured by wizard. I just changed the mode to aggressive and the SA lifetime to 86400. The local subnets are 10.9.8.x and 192.168.4.x. Thank you a lot for any suggestions.4KViews0likes1Comment
