Hello, I made some changes in my topology to avoid some equipments, actually I have the server iron connected directly to my Internet gateway. In order to troubleshoot the nat configuration but I found the mac-address on my outside interface is:
telnet at NAT_CENTRAL#show int eth 16 FastEthernet16 is up Hardware is FastEthernet, address is 0004.8065.3b84 (bia 0004.8065.3b84) But in the network it registered with another mac-addres, Internet 200.62.80.2 0 0204.8065.3b75 ARPA FastEthernet0/1 And i want to known if this is normal, because i look for this layer 2 address on every interface but i didn't find. Is it the cause of the delay on nat Translations ? -----Mensaje original----- De: Tom Samplonius [mailto:tom at uniserve.com] Enviado el: Lunes, 07 de Agosto de 2006 12:14 p.m. Para: Ram?n Alvarez Rayo CC: 'Ryan DeBerry'; foundry-nsp at puck.nether.net Asunto: Re: [f-nsp] Problem with NAT Foundry Server Iron XL Ramon, I find that the XLs are not very tolerant of misconfigurations, and when there are problems, they just perform inconsistantly like this, rather than logging any errors. So I would look for any duplicate IPs, or duplex mismatches, plus any errors on the XL ports, plus any switches/routers that the XL is connected to.
