Hello everybody!!
I'm making a PPPoE server with proxy, the client can connect without problem to the pppoe server and can use internet perfectly. But I want to use the proxy and it is imposible.
In IP FIREWALL NAT I have this rules:
[admin@MikroTik] /ip firewall nat> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=srcnat action=masquerade out-interface=dedicado
1 ;;; Redirecciono el puerto 80 al 3128 para hacer el Web Proxy
chain=dstnat action=redirect to-ports=3128 in-interface=interno dst-port=80 protocol=tcp

Well, the second rule doesn't work, I have the proxy enable!!
I tried, to use the router without PPPoE server, only whit a DHCP server, and in this way the proxy work perfectly!!! But I connect via pppoe and NOT!!!
Can someone say me why? and how I've to configurate the router to make the proxy work, please!!
Thank
Rafael Loré

misconfiguration is in "in-interface=interno": packets are received on pppoe interfaces, not interno. use "in-interface=!dedicado"

Thank you very much!!!
this afternoom I'll try this, I think thas is my problem
Thank

Hello I couldn't wait this afternoom. I tried what you say Chupaka and is OK, it worked, Thank
But I have another question!! What happend if I have 3 ethernet card, where the configuration is this:
1 - DEDICADO, where I have my principal access to internet
2 - ADSL, where I have an access of xDSL to works only with P2P
3 - INTERNO, where the PPPoE server is working
The question is that if I use "in-interface=!dedicado", like you say and work, the interface ADSL, will crash with it, isn't it?
Thank you
Rafael Lore

just remove filtering by interface from the NAT fule, and then drop all packets to port 80 from interfaces adsl and dedicado. it will work =)

if you want better solution, mark all outgoing connections to port 80, and then drop all incoming connections not marked on interfaces adsl and dedicado - you will secure your router from accesing from Internet =)
