PIX breaks outgoing connections?

Hi everybody,

I have a PIX firewall with two interfaces. The internal uses NAT. Everything looks to be ok except for the outgoing data transfers from the inside to the outside subnet. The transfer is interrupted after some few hundreds of KB transferred. It happens when using either ftp or smtp. However, if doing similar transfers to servers in the internet, everything goes well. The problem occurs only when transferring from the inside interface toward the outside one. If traffic goes after the internet router then I have no problem. When getting ftp data from the outside subnet to the inside there is no problem. I have no time/size limits for data transfers set in my servers. Our network provider says it is no restriction set in PIX for outgoing data so where the problem is? It is a bug on PIX?

I have a PIX 515 with two interfaces, running PIX Version 4.4(7)

My network arrangement, from the internet to the inside interface is the following:

router -> outside subnet with e-mail server, web server and DBMS server -> PIX -> inside subnet

Any suggestion is welcomed

Faustino

Re: PIX breaks outgoing connections?

Honestly,

Upgrade your PIX Version. I am currently running 6.1(1)
