The problem is, I can not access printers in two remote sites that have printers with statically assigned IPs. All printers are accessible from other sites, but problem is only when I try to access them from sites that have ISA as Front End Firewall. I have Site to Site tunnels working just fine and no restrictions in tunnel whatsover, since it is encrypted and All Users allowed. I can ping printers and I can even open folders on PCs in remote sites by typing \\192.168.4.9\d$ and folders structure comes on and I can browse, but I get the error when I try to open web interface of the printers. Again, they have all static IPs and are accessible from other sites. I did Monitoring on ISA to catch traffic from my PC when I try to open web interface of the remote printer and I see in monitoring section Error information 0x40 Initiated Connection on http (I don't have https on printers enabled) and after that Failed Connection Attempt on port 80. I do not have Proxy on in my IE and the same is from any PC behind ISA. I talked to 3rd party firewall maker and my traffic in that momnet on port 80 is not even reaching remote fwall. I have tested myself by capturing traffic at the same time and it seems my pings and CIFS when browsing folders remotely are working just fine, but port 80 simply nothing. If it was routing, then I wouldn't be able to ping and browse remotely PCs in other sites, I guess??? Does anyone have an idea? I am sure it is ISA and again, Firewall Policy is OK, since it allows All Users and All traffic between sites -two way direction.
Just as an FYI, if anyone gets into same issue. I have fixed it by changing port on web site of the printers to other then 80, since WEB Proxy filter on ISA was blocking me (THATS GOOD)
