Hi all. My HQ is connected to many different sites using site to site vpn. There is 1 particular site that face a strange problem. Every user in that site could not send email to our mail server over the site to site vpn. However they could successfully do a telnet to our mail server on port 25 using the same link. Internet access and receiving mail is fine, just can't send mail using ms outlook. Same problem occur when trying to use a diff application. I had to reload their pix515 firewall to resolve the problem. My HQ is also using pix 515 to connect to the various sites. Pls advise how i can troubleshoot to isolate the problem. Or is it a hardware problem with the firewall? Pls advise, thks in advance.
