Could you please suggest how to set up NAT 1:1 to route several addresses from the local network VLAN1 to several addresses in VLAN2 (WAN)? I looked in several places - I did not find an answer. On other equipment I succeeded in this part, but I do not know how to do it on the S615. Three WAN addresses: Three LAN addresses: IP1: 90.100.34.2 /24 IP1: 192.168.1.102 /24 IP2: 90.100.34.3 /24 IP2: 192.168.1.103 /24 IP3: 90.100.34.4 /24 IP3: 192.168.1.104 /24 I hope that if we can solve this problem it will be useful for many people on the forum. Of course I will share the working solution as well as answer questions. Best Regards Przemek Attachment s615_forum.png (459 Downloads)

In this case as VLANs are defined, you need create also Firewall rule to enable traffic between these 2 VLANs. I don't have Scalance S615 but NAT is same problematic in case of expected source/destination path.

Finally I create configuration below: Three WAN addresses: Three LAN addresses: IP1: 90.100.34.2 /24 IP1: 192.168.1.102 /24 IP2: 90.100.34.3 /24 IP2: 192.168.1.103 /24 IP3: 90.100.34.4 /24 IP3: 192.168.1.104 /24 This is for 1st -> rest will be similar. Yellow mark is your VLAN you want to connect to. If "devices" should be seen from several VLANs You have to add additional IP + MASK. Kind Regards. Przemek Attachment conf.png (94 Downloads)
