title: SonicWall VPN tunnel is up, but no traffic allowed. Where to begin troubleshooting?
body: <p>I'm have a tunnel between a SonicWall NSA2400 (corp office) and a TZ215W (branch). The VPN link shows to be up, however, traffic counter stays at 0 and I can't ping to the remote network. </p>
  
  <p>It's a site-to-site setup:<br />
  -corp office:<br />
  --IKE preshare<br />
  --IPSec gateways set to 0.0.0.0 (dynamic IP at branch)<br />
  --local IKE ID: ~WAN IP~<br />
  --Peer ID: ~peer's firewall ID~<br />
  --Local net: LAN subnets<br />
  --Remote net: 192.168.0.0 - 255.255.0.0<br />
  --Phase1: IKEv2 > Group2 > AES-256 > SHA1<br />
  --Phase2: ESP > AES-256 > SHA1<br />
  --NetBIOS bcast enabled<br /></p>
  
  <p>-branch<br />
  --IKE preshare<br />
  --IPSec gateways set to ~corp WAN IP~<br />
  --local IKE ID: ~firewall ID~<br />
  --Peer ID: ~corp WAN IP~<br />
  --Local net: LAN subnets<br />
  --Remote net: 192.168.0.0 - 255.255.0.0<br />
  --Phase1: IKEv2 > Group2 > AES-256 > SHA1<br />
  --Phase2: ESP > AES-256 > SHA1<br />
  --NetBIOS bcast enabled<br />
  --Keep alive enabled<br /></p>
  
  <p>The connection status is as follows<br /></p>
  
  <pre>
  Name    Local                           Remote                          Gateway
  corp    192.168.0.0 - 192.168.255.255   192.168.0.0 - 192.168.255.255   ~corp VPN Static IP~
  </pre>
  
  <p>Any obvious pieces I'm missing?</p>
