I am using sangoma S5141 wan card. I have connected my modem to the card in linux machine. The linux distribution I am using is Redhat AS 4, I am trying to replace the cisco router in my office with the sangoma S5141 wan card. I have configured the card in CHDLC where I can able to ping the serial IP, but with 80% of packet loss. And If I browse any http or ftp or any sites I cant able to browse. When I put tcpdump I am seeing the error like one as below, which means the far end is blocking some traffic.
I've not yet had the pleasure (I do want to work with it) of working with any WAN equipment under Linux, as such I can't say much for sure.
IP <source IP:port> > yahoo.com:port host <destination IP> unreachable - admin prohibited
This makes me believe that someone on the remote end is rejecting your traffic. Can you tell what host sent the 'host ... unreachable' message. If the host that sent the message is not on the other end of your WAN link, chances are good that the WAN link has nothing to do with the problem. Rather that someone further out in the net is blocking the traffic.
The protocol status Lip Dev Prot State goes UP and DOWN.
From some quick Googleing it looks like you are dealing with a PPP connection across your WAN, correct? If this is the case, is there a chance that the other end of the PPP connection is unhappy with something about your configuration and thus taking your connection down?
Any ideas would be appreciated.
Speculation is all I really have. Grant. . . . _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
