I have trouble getting the BBSM server functional. Hope someone can help me.
We have installed and configured BBSM 5.2 software on a compaq
proliant ML 370 server following the stpes in the installation and user
manuals. Now none of the clients can browse the internet. If I check the
"enable transparent proxy" or specify proxy in client's browser only browsing works. But the problem is that applications like Yahoo messenger, msn messenger do not work. I do not want to enable the transparent proxy. What could be the problem?
Please find below the details of BBSM software configuration:
service pack - 1
patches - PMS fidelio patch
Server hardware - Compaq
External NIC - Compaq NC3163 Fast Ethernet NIC
IP Address: 192.168.34.5
Subnet Mask: 255.255.255.0
DNS : 127.0.0.1
Default Gateway: 192.168.34.2 (IP address of the DMZ interface of the
PIX 515E Firewall. Since I had a doubt about the firewall causing the
problem, I have tried bypassing the firewall by directly connecting the
server's external NIC to the router and changing router's ethernet IP
address to 192.168.34.2. But there is no difference.)
Internal NIC - D-Link DFE-550TX FAST Ethernet 10/100 Adapter
IP address 192.168.32.5
subnet mask 255.255.255.0
No Default Gateway
DNS : 127.0.0.1
Switches used - Core switch - Cisco 3550 - IOS 12.1(11)EA1
Client switches- Cisco 2950 - IOS 12.1(11)EA1
Status of the BBSM server -
Switch discovery wizard completed succesfully.
Able to map rooms and run port test succesfully
When browser is set with proxy server browsing works
When "enable transparent proxy" is checked - only able to browse
When "enable transparent proxy" is unchecked - no internet connection
from clients.
Enabled forwarding on the DNS server by specifying ISP dns server IPs as forwarders. Name resolution takes place meaning that when I try to ping to a hostname, It resolves the name to its IPaddress. Also not able to browse using IP address of web site from client PC, but it is possible from the server.
Also noticed the following error in the windows event log:
Event ID: 20106
Description: Unable to add the interface Internal with the Router
Manager for the IP protocol. The following error occurred: The parameter
is incorrect.
I read posted message that all switch ports should be mapped in order for BBSM to operate correctly. Is this true?If this is correct do I need to map only those number of ports which I have specified as No. of client ports in the switch configuration? This is because we are not using all the ports on a switch for BBSM clients.
TIA

I am not sure though, one thing that is bothering me is the DNS addresses configured on both the NICs. It is pointing to 127.0.0.1, a loopback address. Wondering how is the name resolution is working.

Make sure you have a route inside statement on your firewall. check whether or not you've added forwarder records. I also made a new zone within DNS for the domain name you are using and added a record for the bbsm server.

Hello,
I'm having exactly the same difficulties as you, I have the outside interface of the BBSM directly connected to the internet router ( no pix in the middle)
and what I see, ( at least my bigger problem) is that https does not get forwarded, and I suspect that any other applications using different ports besides port 80 doesn't also.
I've already opened a tac case, but the answer wasn't that clarifying.
May it be a bug?
I saw in ISA server management that on the protocol rules ALL IS OPEN! so why doesn't it work? Is it related to the start pages? or is the atNat driver performing in a way that overrides the ISA server configuration.
When sniffing a client PC and the internal interface I can see the packet with destination 443 leaving the client, but it does not arrive to the inside interface. Perhaps the driver is lower level that the sniffer I'm using, and interceps the packets.
Sorry about the confusing post, but at least be assured that you're not the only one with this problem.
