Unable to browse to certain websites. Any suggestions?
I setup a doctor's office with Internet access using Covad's DSL network using a Netopia DSL modem acting as a dedicated bridge and a Cisco 871 router acting as the PPPoe client.
I was able to get the router to authenticate and allow Internet access to sites such as AOL, MSN, craigslist, but some of the websites such WebMD would just stall and sit there. You would see the banner page at the top of the browser window but the content would not download and display. Does anyone know from this scenario whether this could be the DSL modem or the router?
Now we configure one FastEthernet interface for use as our WAN interface.
interface FastEthernet 4 description ADSL WAN Interface shutdown pppoe enable pppoe-client dial-pool-number 1 ip nat outside no ip address no ip redirects no ip unreachables no ip proxy-arp no ip mroute-cache no cdp enable no shutdown exit
Now to add your Dialer interface:
interface dialer 0 description ADSL WAN Dialer shutdown ip address negotiated ip mtu 1492 encapsulation ppp ip nat outside encapsulation ppp ppp authentication chap callin ppp chap hostname ppp chap password dialer pool 1 dialer-group 1 no ip mroute-cache no ip unreachables no cdp enable no shutdown exit
dialer-list 1 protocol ip permit
interface vlan 1 description ADSL LAN Interface shutdown ip nat inside ip address a.b.c.3 255.255.255.0 no ip redirects no ip unreachables no ip proxy-arp no ip mroute-cache no cdp enable no shutdown exit
access-list 10 permit a.b.c.0 0.0.0.255
no cdp run
