![]() In practice, I can't get 10.10.x.x addressing working over tunnels. This should also be able to connect branch offices, but I have same problem. Also tried to add same routing rule to the 元 switch routing table where VirtualHUB belongs to.Īdditionally I have road warrior which uses 192.168.30.x address. Iptables -t nat -I POSTROUTING -s '192.168.1.0/24' -o tun0 -j NETMAP -to '10.10.10.0/24'īut how I should set routing and interfaces on SoftEther server to get it working? In order to point it to 192.168.2. I have found this picture to be very useful. iptables -A INPUT -i tap+ -j ACCEPT iptables -A FORWARD -i tap+ -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o eth0 -j MASQUERADE On the client, the default remains to route via 192.168.1.1. iptables -t nat -A OUTPUT -p tcp -dport 4567 -j REDIRECT -to 8443. Since in this case its all local, then one must use OUTPUT instead of PREROUTING to redirect the packets. Iptables -t nat -D POSTROUTING -s '192.168.1.0/24' -o tun0 -j NETMAP -to '10.10.10.0/24' PREROUTING works on network packets, for instance what you would get on a router device. I should be able to connect for each device in branch offices from the application server by using 10.10.x.x IP addresses. Could you help me with configuration to get routing working. But for the various reasons I would like to get it also working with SoftEtherVPN. ip firewall nat add chain=srcnat src-address=10.10.10.1-10.10.10.254 action=netmap to-addresses=11.11.11.1-11.11.11.Following scenario I'm able to get working with OpenVPN. If you want to link a WHOLE Public IP Subnet (say 11.11.11.0/24) to a Local Private IP Subnet (say to 10.10.10.0/24), you should use Destination address translation and Source address translation With the "action=netmap". ip firewall nat add chain=srcnat src-address=192.168.0.109 action=src-nat to-addresses=10.5.8.200 Example of 1:1 Subnet Mapping. by having its source IP Address translated to 10.5.8.200): ip firewall nat add chain=dstnat dst-address=10.5.8.200 action=dst-nat to-addresses=192.168.0.109Īdds a rule that allows the Internal Server to talk to the Outer Networks (ie. ip address add address=10.5.8.200/32 interface=PublicĪdd a rule that allows access to the Internal Server from the External Networks: Add a Public IP Address to your "Public" interface:.Please note - for that to work, you should also use Source Network Address translation (please ref. This is done to allow the Local IP Address to talk to the Public IP Address. ip firewall nat add chain=srcnat action=masquerade out-interface=PublicĪbove example shows you how to configure NAT on a Mikrotik router.ĭestination NAT is used to “ link” the Public IP Address (say 10.5.8.200) to the Local IP Address of your liking (say 192.168.0.109). Iptables and ip6tables are used to set up, maintain, and inspect the tables of IPv4 and IPv6 packet filter rules in the Linux kernel. To use masquerading, a source NAT rule with action 'masquerade' should be added to the firewall configuration: ![]() I'll need something like: ip6tables -t nat -A POSTROUTING -o eth0 -s fc00::/64 -j NETMAP -to 2006::/64 to nat the addresses to global addresses (and with proper dnat rules) But I can not find anything like that in nftables. ![]() Used to “hide” the private source IP Address (i.e.:192.168.1.109), aka masquerading. Then I'm considering about using unique local addresses. ip firewall nat add chain=srcnat src-address= action=netmap to-addresses= Source NAT. ip firewall nat add chain=dstnat dst-address= action=netmap to-addresses= Example of 1:1 Public-to-Private IP mapping.
