External ip use for internal serveur

[Guest]

Hi all,

my endian config is:

3 red nic why 3 external ip.
internal serveur use nic 1 to going to internet when it's port 80
computers use nic2 to going to internet when it's port 80

so with endian 2.4 i have create postrouting rule iptables -t nat -I POSTROUTING -s 192.168.1.0/24 -d 192.168.1.81 -p tcp --dport 80 -j SNAT --to-source external ip nic 1 and it's works.

but i have installed endian 2.5 and it's not work

do you have any suggest to correct it ?

Tks

Under the firewall, go to the tab incoming routed traffic. Create a rule source being your external IPs and allow those external IPs to destination any.

Hope this helps. I am runnig server behind Endian on external IP and all i have done is allowed Ip in incoming routed traffic. And yes in your cse you also have to create a. Route under network.

tks for your reply

in my case it's not work. maybe cause my configuration.

i have specific rule to use uplink 2 when it's port 80. when we use serveur external ip, it use ip of uplink 1.

so the client use this to going to external ip (http://external_ip_uplink1) -> internet Uplink2 -> Uplink1 -> Serveur

Have you restored the configuration from 2.4 to 2.5?

Yes i have restore it, and it's here that i see my last configuration not works.

edit if i use uplink 1 to going to external ip of uplink1 it's work but not use uplink2 to going to uplink1

I found solution

i have created policy routing to use ip of gateway when it's external ip of serveur
for exemple

my gateway ip is 192.168.1.253
my external ip si external ip
network is 192.168.1.0/24

create route policy

source 192.168.1.0/24
destination external ip
uplink ip_gateway green 192.168.1.253
