General Discussion / Wifi to dmz

« on: December 15, 2021, 05:35:38 am »

Hi all

I have this opnsens

192.168.1.1 opnsens  (all in mask /24)
   ---------------------------------------------
    - wan 192.168.0.1
    - lan 192.168.1.1
    - dmz 192.168.2.1
    - wifi 192.168.4.1  + (dhcp range ( .4.5 to .4.20)

    ---------------------------------------------



I try to reach serveur in dmz from wifi client.
   like this : ping 192.168.2.10 (web serveur)  from 192.168.4.10 but no way.


   and i get allways a : Block deny rule when i try to access 192.168.2.10 from a webrowser in wifi client 192.168.4.10
 i have got a deny  : src 192.168.2.10:80 dst 192.168.4.10:55120 default deny rule


All is working, wifi client can access internet, except that i cant access my Web service  in dmz from wifi client.

I have added a rule like this
Pass 192.168.3.0 http  192.168.1.4 (Web serveur) any

wifi users can access to internet and lan users but not dmz serveur
lan users and internet users can acces to my webserver in dmz.

Something is wrong....
Any help is welcome

16.7 Legacy Series / [SOLVED] pptp redirect

« on: November 29, 2016, 05:22:44 pm »

Hi all,

I have a pptp server inside my lan (192.168.1.99)  and want to reach it by client pptp

i've found this info:
"The PPTP server redirection mode has been removed. It can be emulated by the two following NAT port forward rules: From incoming WAN interface, redirect all traffic to PPTP server IP target for protocol GRE. From incoming WAN interface redirect all traffic to PPTP server IP target for protocol TCP, port 1723. Note that due to the design of GRE, only one server can be reached by incoming clients at any given time."

with last  last update pptp was removed

I suppose that for me, It'snt necessary to add this plugin because my server is inside the lan, and i want to redirect correctly the vpn connection to my pptp server

so, i have added two Nat redirection : GRE and tcp/1723 from WAN to LAN 192.168.1.99

But that doen't work !

What i have missed,

Thank for any help

config opnsense ip :192.168.1.1
