However security best practices dictate that it is a good idea to explicitly set a VPN community in the VPN column, which ensures that traffic is being matched to the rule and handled the way you expect (i.e. being encrypted or decrypted and not just being sent in the clear where it is vulnerable to eavesdropping).
Oct 19, 2015 · IPSec VPN traffic works only one way Hello everyone, I'm having a bit of trouble getting our VPN to work properly. Both routers are Fortigate 60B running 4.0MR3P18. The tunnel comes up fine and I can initiate any type of traffic from the branch network to the head office network (i.e. ping, VMware, active directory, file sharing, etc.) but if I try to do the same from the head office to any One Way Issue with VPN Tunnel. Site C and the remote offices will send 95% of their traffic to Site A and the rest to Site B, there is very little if any traffic However security best practices dictate that it is a good idea to explicitly set a VPN community in the VPN column, which ensures that traffic is being matched to the rule and handled the way you expect (i.e. being encrypted or decrypted and not just being sent in the clear where it is vulnerable to eavesdropping).

This can be seen inside of Network > IPSec Tunnels. Confirmation. In order to confirm this is the issue, please run the CLI following command multiple times, once before and once after trying to send data across the VPN tunnel: In this scenario there is an active Site-to-Site VPN tunnel up on the SonicWall and the remote device but traffic will only pass in one direction, either from the SonicWall to the remote site or vice versa.
For the test though we only want one machine's traffic to be pushed through this tunnel. I was told there is a way to limit the tunnel traffic with an additional ACL, but I'm unclear as to how to achieve this and still allow all other traffic through the outside interface as usual.
Additionally, rules are also created to allow traffic to and from the networks defined under "Remote Subnets" in the VPN network creation. The solution is to disable auto-firewall and then accommodate for what that does under the hood, by manually adding the proper rules on WAN_LOCAL, and excluding the IPsec traffic from NAT.

FTD VPN One Way VPN Traffic Warning! At this point if you configure the ASA, the tunnel will come up, and if you’re behind the FTD everything will work. But If you’re behind the ASA and you want to talk to anything behind the FTD, it wont work.
I created a Virtual Network (VPN) on Azure and provided an ample address space 10.0.0.0/16, then I made a couple subnet within the network, one for the gatewaySubnet (10.11.1.x), and another for the VMs inside (10.11.0.x), I can go though and ping to the other side, but the other side cannot ping me.
Flow preferences seem to only allow you to select wan 1 or wan 2 as the route for the traffic. I can't see a way to say specific traffic only uses the VPN. Unless I am missing something. The screen shot below shows that the preferred uplink is only wan1 or wan2. If there was an option there for vpn then I think it would work. Dec 22, 2019 · Solved: Team, Currently have a Site to Site VPN up and working fine using a ASR to ASR. I replaced the one of the ASRs for an ASA. The site to site is up.

VPN tunnel passing traffic only one direction. the tunnels are up fine and I'm once again in the same position of traffic only working one way. I double checked I've seen this exact situation (one-way VPN) when a Cisco ACL was blocking IKE/ESP in one direction. ACLs can be stateful with the "established" rule. Once traffic is established it will allow the return traffic. Easy enough to check, either on the router if possible, or the firewall.
