i'm setting up a new 1811 and also relatively new to ios.
here's the basic layout:
t1
|
-> cisco 1811 (fe0 = 38.104.x.x, wan; vlan1 38.111.x.201, lan)
|
-> firewall (38.111.x.203) -> separate network, servers, etc. (unknown beyond this point)
|
-> sonicwall (38.111.x.202) -> lan 10.0.57.1 (nat, firewall)
so we're basically setting up the lan side of the cisco to act as the wan side for each of the other routers/firewalls.
my problem is that i can't route out from the lan side as of right now. outbound pings and traceroutes from the 1811 succeed but not from a client attached on the lan side (one of the 1811's switch ports on vlan1).
the routing looks like this:
Gateway of last resort is 38.104.x.97 to network 0.0.0.0
38.0.0.0/8 is variably subnetted, 3 subnets, 2 masks
S 38.111.x.0/29 [1/0] via 38.104.x.97
C 38.111.x.200/29 is directly connected, Vlan1
C 38.104.x.96/30 is directly connected, FastEthernet0
S* 0.0.0.0/0 [1/0] via 38.104.x.97
how can i configure this box to allow inbound and outbound routing? we're not using any filtering or acls on either fe0 or vlan1. it also seems i can't get anywhere without a static route in place as indicated above.
this is probably elementary routing, but i'm unfamiliar with the ios syntax. thanks for any help.

While this is not causing a problem, you don't need a static route to the inside:
"S 38.111.x.0/29 [1/0] via 38.104.x.97"
and this static does not fall within your assigned subnet:
"C 38.111.x.200/29 is directly connected, Vlan1"
Can you ping from the 1811 while sourcing from Vlan 1?
If you can't, then I suggest contacting the ISP and make sure they are advertising 38.111.x.200/29 towards the internet.

thanks, edison. i'll give them a call.
outbound pings from the 1811 itself work but not from a client on the lan side.
i assume the static routes won't be needed if the isp can take care of the other route advertisement, correct?

Correct.
