I have 3g usb modem UM175 I have setuped ppp connection thru usb1 and my modem has been connected (entered login password phone to call disable call on demand)…

I can ping any ip from router console.
I can ping any ip from PC (wireless connection to router)
I can’t open any page at router (err connection reset)
I can remotely connect thru winbox from other PC thru internet…

At firewall I have some default rules and one NAT rule interface out ppp-connection masq…

When I first time setup that everything is works after turning off router I have that issue…

I can attache config files…
I really need help Couse I need to setup that router to customer tomorrow until today I think that it’s ok but when checked I was disappointed…

I will be where appreciated for any advices.

Are you saying that your only problem is:
I can’t open any page at router (err connection reset)

How are you trying to “open page at router” ???

If you are saying you can ping ip addresses, but not open websites on the PC, then you need to setup DNS on the router or the PC.

Sorry for misunderstanding.
Problem that I can’t load any page on end pc except one page ukr.net (I don’t know why is loading) if attache modem to pc everything is working…

DNS at pc is working I can ping any page and get right IP address and respond…

you need to post your config. It’s not possible that router accidently decided to give one page access, and block the other pages.

I have don’t touch anything but it start working … very strange …

I have any trouble agan i will post
