SKY Sagem f@st 2504. Help with firewall configuration.

[mark.h]

Hi all.

Im hoping i might be able to get a little help configuring my Sagem f@st 2504 router?

I am using Ubuntu 8.04 as my O/S and firestareter as my firewall. So I know all ports are stealthed on my PC.

But the problem lies with a few open ports opened through my router.

I'm a relative newbie, so all this is slightly overwhealming at the moment, and im not even sure i am asking the correct questions??

Can anybody Help me to configure my firewall rules on my router?
The ports that are show up when I scan all ports on my router using ShieldsUp from GRC are:

21 ftp
23 telnet
53 domain
80 www
1863 msnp
1864 unknown
4443 unknown
5190 aol
5431 unknown
5566 unknown
30005 unknown

I do know some need to be open and stealthed to not show up on the internet. but six are actually open and not stealthed.
They are: 1863, 1864, 4443, 5190, 5431, 5566, 30005.

I hope i have explained my issue clearly enough to get some help...

Cheers for know.

Looks like this is proving to be quite tough to get any help at all with this issue??

Does anyone know where I can get a manual/Instructions for my router (Sagem f@st 2504 SKY)

I don't have a Sagem, but if it's anything like the Netgear, the default firewall rules allow everything outbound and nothing inbound. If you wish to limit outbound traffic (maybe you are controlling outbound traffic from untrusted sources on the LAN as is done on corporate networks) then just create outbound firewall rules.

With respect to the ports you are seeing, they access services on the router itself (as in LAN --> router*) and are not ports "opened through your router" (as in LAN --> Internet).

(Technically, some are application level gateways: LAN --> router --> Internet, but that doesn't matter here. The important thing is that you are protected from inbound nasties.)
