I pleaded for help from you because of all the PC clients can not access the internet unless they
access it via a proxy.
I'm using Usergate version 5.
Server has 3 interfaces. 1 WAN and 2 LAN. WAN interface connected to the ADSL modem . One of the LAN interface connected to the router (we call it LAN 1). Other LAN interface serves as a proxy access (we call it a LAN 2).
configuration interface IP address as follows:
WAN: IP: 220.127.116.11/24
GW: 18.104.22.168 (ADSL modem IP address)
DNS: from ISP.
1. I use router because in my office there are 2 gateway, one for office's application and the other for internet. sorry i dont mention it before.
Every PC clients connected to a catalyst switch, which connected to 2 router, one is for gateway for office application, and a mikrotik router. PC gateway is mikrotik address.
2. LAN2 connect to Catalys switch. I use this interface. because, at earlier phase of usergate installation, i set usergate only for internet sharing (proxy) that control internet access.
i set every PC's browser with this address proxy (172.25.61.155).
When i want to put usergate to firewall, I added new NIC n changes address, but i dont want other user to lost connection to internet while i configure the server, so i let the proxy interface (LAN 2) stay there.
I have planned to remove LAN2 interface, if connection OK.
I hope my explanation can help you to figure this out..
Thank you one more time for your coorperation
