Admin page doesn't load after changing WAN access port

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I changed WAN access port (was 8080 - worked perfectly, now - 8081)
2. Restarted router
3. Admin page doesn't show up - Problem loading page, can't establish a 
connection

What is the expected output? What do you see instead?
Admin page is expected requesting login/password

What version of the product are you using?
RT-N16, r3300

Please provide any additional information below.
SSH connection works well

BTW, where (probably some configuration files) i can find saved preferences? 
Particularly conf for httpd?

Upd: start up new httpd on port 8008, create virtual server for incoming port 
8008 and forwarded it to 192.168.1.1 (router ip) on port 8008. But I can not 
access my http server on 8008 port from WAN. From LAN it works perfectly well.

it's obviously wrong setup.
set "Port of Web Access from WAN" to 8008 and everything will be fine without 
any need for manual starting, vserver rules adding etc.

As I wrote originally I set up "Port of Web Access from WAN" to 8081, but admin 
page was unavailable.
Additional information with httpd and forwarded port is only another example 
that port forwarding doesn't work.

Despite issue is invalid could you suggest what can I do to make port 
forwarding work? I changed WAN Access port back to 8080 through Admin page 
yesterday from home. But now I can not connect to admin page from work 
(although I managed to do this previously).

please provide iptables -nvL, iptables -t nat -nvL output
p.s you can hide last octets of wan ip address in ip4.ip4.xxx.xxx form

find "tcp dpt:8080 to:192.168.1.1:80" in your iptables -t -nvL output.
it means you've set access port to 8080, just tried to open your wan 
address:8080 and it worked.
so, it's really invalid issue. please confirm

I'm able to open admin page now.
but address:8008 still is not working although "tcp dpt:8008 
to:192.168.1.1:8008" presents in iptables -t nat -nvL (it was configured using 
admin page > Virtual Server).

ok, this seems to be misconfiguration of virtual server. Close the issue

yes, it will not, but to:192.168.1.1:80 will.
as I said before, it's obviously wrong setup.
