I have set up this firewall for default configuration. The internal network works fine. I connected the internal interface of the dsl modem to the external interface of PIX 501 firewall. I configured the firewall connection to PPOE. The firewall connects and acquires the web ip address. I made sure that all ports are open for tcp, udp, igmp, ip protocols for traffic coming from internal networt to outside.
I am not getting dns resolution for external sites. How can I check assigned ip configuration, (ip address, gateway ip, dns, etc) of my router on external interface assigned by PPOE connection?
Does this firewall run dns server? Is there a place I could configure farwarders?
In PPOE configuration, does it matter if I set the authentication to pap as opposed to chap or mschap?
Any suggestions would be greatly appreciated.
Thanks in advance
