![]() Traffic from the internet to the internal servers works fine.īut the traffic from the internal clients ends up at IF eth1 (WAN2) instead of eth4 (LAN-Servers)Ġ6:31:17.036168 IP 10.0. Set nat source rule 471 translation address masquerade Therefore it is the Vodafone router that needs to be doing NAT loopback (even then Im not 100 sure it would work with double NAT). Assuming your DDNS is setup correctly it will point to the WAN IP address of the Vodafone router. Set nat source rule 471 destination port ‘315’ Your issue is caused by having double NAT (one router behind another). Set nat source rule 471 destination address ‘10.0.1.29/32’ There are three available choices for NAT Reflection mode for port forwards, they are: Disable. Configure the NAT Reflection options as follows: NAT Reflection mode for Port Forwards. Locate the Network Address Translation section of the page. Set nat source rule 471 source address ‘10.0.0.0/8’ To enable NAT Reflection globally: Navigate to System > Advanced on the Firewall & NAT. Set nat source rule 471 outbound-interface ‘eth4’ Upon further research soem suggestions received in sto implement Split DNS. Reached out to CPanel and they said that NAT loopback is not enabled an the network which is causing their Auto SSL and some other services to work incorrectly. Set nat source rule 470 translation address masquerade Have enabled NAT Reflection on the pfsense firewall as recommended. Set nat source rule 470 destination port ‘315’ Set nat source rule 470 destination address ‘91.112.x.x/32’ Set nat source rule 470 source address ‘10.0.0.0/8’ Set nat source rule 470 outbound-interface ‘eth4’ Set nat destination rule 700 translation port ‘315’ Set nat destination rule 700 translation address ‘10.0.1.29’ ![]() ![]() Set nat destination rule 700 protocol ‘tcp’ Set nat destination rule 700 inbound-interface ‘any’ Set nat destination rule 700 destination address ‘91.112.x.x’ Hair-pinning also known as NAT loopback is a technique where a machine accesses another machine on the LAN or DMZ via an external network. The most popular technique for TCP NAT traversal is TCP hole punching. Another way is to use various NAT traversal techniques. One way to solve this problem is to use port forwarding. Set nat destination rule 700 destination port ‘315’ Viewed 2k times 2 Id like to understand why trying to connect to a server in the same network, using the public IP address (provided by the router/NAT), and the port doesnt work. The NAT traversal problem arises when peers behind different NATs try to communicate. I’m trying to setup a NAT rule for one internal server and want to access it with the IP 91.112.x.x of eth0 (WAN1) from 10.0.6.10 from eth6 (LAN-Clients) to 10.0.1.29 eth4 (LAN-Servers) I’m running vyos with the following config: ![]()
