Suddenly from yesterday there is no incoming mails. I can send without any problem but I can't receive any mails. I have 2 exchange 2007 servers. One with client access role and one with mailbox and hub transport. Any ideas where I should start looking?

Hi,
I would suggest the following:
- check if MX records are pointing to your HUB transport
- try to telnet 25 port of your hub transport

Any changes that you know of happening 2 days back?

Are you using Dynamic DNS, if so check if you might have gotten a new public IP that hasnīt been synchronized with your Dynamic DNS provider.

Try telneting to port 25 of your external name (MX-record).
Do you NAT / Port Forward in Firewall? Check there so that all is ok.
DO you see any evidence of external mail in your SMTP logs at Hub Transport?

I have checked both mx records and ports and everything is ok.
The crazy think is that if I send an email in gmail the press reply I receive it. But when I compose a new email from gmail I never receive it.

I would suggest you to have a look at the header of the email received in gmail (this can be found when you open the message and choose "Show original" from the combo box) and check if the sender information is correct.
br,

When sitting at an external Internet connected host, try telneting to your mail server and send a manual mail.

Speak SMTP like a native

Ensure You have PTR record
Are you able to find MX record from NSLookup
Any changes were made in the mail server or domain.
If everything is fine check Receive Connector.

So there's your change from 2 day's back.

Working NIC - Faulty NIC
