If I run tcpdump -i vpnt1, it doesn't capture any packets. I'm using the default encryption and data integrity value for the Azure gateway in IKE V2. I configured VPN domains as empty groups in the checkpoint, configure the vpnti and a static route through it. I'm trying to establish a route based VPN between a checkpoint Iaas single gateway R80.10 (in Azure) to an Azure Virtual Network Gateway. I didn't get an answer for either ssh or ping communication.ģ.- tcpdump host (public IP of my Azure gateway) sending an SSH command from a VM in the checkpoint network to a VM in the Azure network:ġ8:04:10.204280 IP 137.117.45.100.isakmp > checkpoint.isakmp: isakmp: phase 2/others ? #37ġ8:04:10.206465 IP checkpoint.isakmp > 137.117.45.100.isakmp: isakmp: phase 2/others ? #37ġ8:04:12.211492 IP 137.117.45.100.isakmp > checkpoint.isakmp: isakmp: phase 2/others ? #37ġ8:04:12.213526 IP checkpoint.isakmp > 137.117.45.100.isakmp: isakmp: phase 2/others ? #37 This appears until I kill the ssh command, and then I keep watching the same output of test 1. I was able to made some more complete tests using tcpdump, which I summarize here (all the time, the tunnel is shown as UP in Smart Monitor, and the connections is either Connected or Succeeded in Azure, showing some traffic).ġ.- tcpdump host (public IPof my Azure gateway) without sending any commands:ġ7:57:56.334561 IP checkpoint.isakmp > 137.117.45.100.isakmp: isakmp: phase 2/others ? #37ġ7:57:58.334778 IP 137.117.45.100.isakmp > checkpoint.isakmp: isakmp: phase 2/others ? #37Ģ.- tcpdump host (public IP of my Azure gateway) sending an SSH command from a VM in the Azure network to a VM in the checkpoint network:ġ7:59:22.248027 IP checkpoint > 137.117.45.100: ESP(spi=0xd4e6b1f0,seq=0x7b), length 100ġ7:59:22.249553 IP 137.117.45.100 > checkpoint: ESP(spi=0xb1a8503e,seq=0x93), length 100ġ7:59:22.249660 IP checkpoint > 137.117.45.100: ESP(spi=0xd4e6b1f0,seq=0x7c), length 100ġ7:59:22.251467 IP 137.117.45.100 > checkpoint: ESP(spi=0xb1a8503e,seq=0x94), length 100
