Hi All, |
2 |
|

I think that I have confused myself with this. I am behind a firewall/http |
4 |
proxy which seems to only allow outbound connections on ports 80 & 443 for |
5 |
web browsing. This is not enough for me, as I would like to use my mail |
6 |
client to send and receive mail from behind the firewall. |
7 |
|
8 |
I tried connecting to ssh servers which listen on different ports, besides |
9 |
tcp/22 and I was not successful. This is probably an indication that the |
10 |
internet gateway machine only accepts connections for packets that have a |
11 |
destination to ports 80 & 443. |
12 |
|
13 |
If the above is correct, am I right to assume that to be able to run a tunnel |
14 |
through this internet gateway I should run something like: |
15 |
|
16 |
ssh -L 2222:localhost:443 me@remote_sshd.com |
17 |
|
18 |
or are ssh packets somehow distinguishable by their headers, so that a |
19 |
cleverly crafted firewall will still identify them and drop them? |
