<description><![CDATA[<A HREF="/useremail/u/0"><b>anon</b></A> : Lol.. Well problem solved. Apparently you need to check a checkbox to enable NAT on this thing while configuring the dsl connection.. It seems a little silly that a <u>router</u> wouldn't have this enabled by default.<br><br>Thanks anyway!]]></description>

<description><![CDATA[<A HREF="/useremail/u/0"><b>anon</b></A> : I'm trying to upgrade my old Speedstream 4100 to a DSL/Router for more network expandability. I'm flat out of network ports/cards and I have another computer that needs connecting.<br>This Router/DSL modem thing is driving me nuts!<br><br>I entered the DSL connection settings exactly from the old modems technical readout. I entered my login and password information and it appeared to establish a connection. It's showing all green on the DSL diagnostics page and it's even being assigned a WAN ip address. For some reason I still have no connection to the internet!<br><br>Diagnostics:<br>Test your Ethernet Connection: &#9;PASS <br><br>Test the connection to your DSL service provider<br>Test ADSL Synchronization: &#9;PASS <br>Test ATM OAM F5 segment ping: &#9;PASS<br>Test ATM OAM F5 end-to-end ping: &#9;PASS<br><br>Test the connection to your Internet service provider<br>Test PPP server connection: &#9;PASS <br>Test authentication with ISP: &#9;PASS<br>Test the assigned IP address: &#9;PASS <br>Ping default gateway: &#9;PASS<br>Ping primary Domain Name Server: &#9;PASS<br>Test Loopback IP:  (suspiciously blank but not fail)<br><br>Routing info:<br>Flags: U - up, ! - reject, G - gateway, H - host, R - reinstate<br>D - dynamic (redirect), M - modified (redirect).<br>Destination         Gateway             Subnet Mask  &#9;  Flags<br>76.210.151.254   0.0.0.0                255.255.255.255  UH&#9;<br>192.168.0.0        0.0.0.0                255.255.255.0     U<br>0.0.0.0              76.210.151.254     0.0.0.0               UG<br><br>Connection Info:<br>Line Rate - Upstream (Kbps):  &#9;512<br>Line Rate - Downstream (Kbps): &#9;3008<br>LAN IP Address: &#9;192.168.0.2<br>Default Gateway: &#9;76.210.151.254<br>Primary DNS Server: &#9;68.94.156.1<br>Secondary DNS Server: &#9;68.94.157.1<br><br>From the routers log:<br>kernel: ADSL link up, fast, us=512, ds=3008 <br>pppd[336]: PPP server detected.<br>pppd[336]: PPP session established. <br>pppd[336]: PPP LCP UP. <br>pppd[336]: Received valid IP address from server.

Why can't my machines do the same? It's almost like this router is giving its clients the cold-shoulder. What can I do to fix this?<br><br>Thanks for any help anyone could give me. I'm pulling my hair out over this thing..<br><br>Also I just noticed an odd entry appearing in the routers log file:<br> &#9;kernel: Intrusion -> IN=ppp_0_35_1 OUT= MAC= SRC=70.83.186.5 DST=76.210.150.144 LEN=48 TOS=0x00 PREC=0x00 TTL=114 ID=24162 DF PROTO=TCP SPT=2235 DPT=21579 WINDOW=65535 RES=0x00 SYN URGP=0 ]]></description>
