hotspot problems (again)

cylent · Sun Jan 13, 2008 7:51 pm

This is sort of part 2 of my previous thread but things are a bit different now.

Problem: Hotspot page takes forever to appear and timesout most of the time.
I do get an IP on the client machine however the hotspot page takes a very long IF it decides to appear. 99% of the time the hotspot page does NOT appear.

Heres the configuration I have:

first the interfaces:

[paul@MikroTik] /interface> print
Flags: X - disabled, R - running, D - dynamic, S - slave 
 #    NAME                                               TYPE             MTU  
 0 R  eth1-builtin-INET-IN                               ether            1500 
 1 R  eth2-EXT-INET-OUT                                  ether            1500 
 2 R  wlan1                                              wlan             1500 
[paul@MikroTik] /interface>

Now, IP's for the interfaces:

[paul@MikroTik] /ip address> print
Flags: X - disabled, I - invalid, D - dynamic 
 #   ADDRESS            NETWORK         BROADCAST       INTERFACE

IP Pool: (i decided to share it between both wlan and eth hotspot networks)

[paul@MikroTik] /ip pool> print
 # NAME                                                                       RANGES

[paul@MikroTik] /ip pool>

and now for the NAT: (now since this is RC14 i dont know if there are errors but i did find after doing the hotspot setup there were invalid NAT entries that I decided to delete since they were not working anyhow.

[paul@MikroTik] /ip firewall nat> print all

I know this maybe a lot to put together but i am really lost and cant figure out why hotspot is acting the way it is.

pls help

Greetings!
Try:
/ip dns print
Usually the "slow-to-failing login page" problem is due to incorrect dns settings.

Thanks for reminding me. I forgot to share those values.

They are correct though;

That is what I thought.

/ip dns set allow-remote-requests=yes

That should take care of the problem (EDIT:) IF those IPs are in fact valid DNS servers.

That still did not solve the problem.

i even did a /system reset TWICE

when i do a system reset i am performing the following steps:

i pull up interfaces, rename the interfaces so i know whats what.
i then enable the WLAN interface.

I assign the interfaces IP like so

[paul@MikroTik] ip> address print
Flags: X - disabled, I - invalid, D - dynamic 
 #   ADDRESS            NETWORK         BROADCAST       INTERFACE       
 0   10.223.167.99/27   10.223.167.96   10.223.167.127  INTERNAL-NET--IN
 1   172.16.0.1/16      172.16.0.0      172.16.255.255  wlan1           
 2   10.0.0.1/24        10.0.0.0        10.0.0.255      EXT--ETH-HOT    
[paul@MikroTik] ip>

then I add the route to the gateway satellite modem:

[paul@MikroTik] ip route> print
Flags: X - disabled, A - active, D - dynamic, 
C - connect, S - static, r - rip, b - bgp, o - ospf, 
B - blackhole, U - unreachable, P - prohibit 
 #      DST-ADDRESS        PREF-SRC        G GATEWAY         DIS
 0 A S  0.0.0.0/0                          r 10.223.167.97   1  
 1 ADC  10.0.0.0/24        10.0.0.1                          0  
 2 ADC  10.223.167.96/27   10.223.167.99                     0  
 3 ADC  172.16.0.0/16      172.16.0.1                        0  
[paul@MikroTik] ip route>

then i create TWO hotspot servers. One for the EXT interface and one for the WLAN inerface.

I then walk up to a close point where i can get a connection. I get an IP automatically and i open Internet Explorer then i get a timeout. No login page or anything.

If i were to type in the gateway IP according to the DHCP ip information the laptop gets I get the logon page. I login but i still cant browse.

and yes. I do have "Allow remote requests" enabled (checked)

I even tried with 4.2.2.2 as DNS servers. STILL nothing.

SurferTim · Sun Jan 13, 2008 11:43 pm

I am not going to go through all the firewall stuff right now, but you should take a look at your dhcp server ip pool. You need to get those IPs in a range where they are localnet to each interface (in the same netmask). Now they are local to neither.

ok well i reset again and this time i only created a hotspot for the ether2 interface.
i setup the IPs like so:

[paul@MikroTik] > ip address print
Flags: X - disabled, I - invalid, D - dynamic 
 #   ADDRESS            NETWORK         BROADCAST       INTERFACE     
 0   10.223.167.99/27   10.223.167.96   10.223.167.127  ether1-inet-in
 1   172.16.0.1/24      172.16.0.0      172.16.0.255    wlan1         
 2   10.0.0.1/24        10.0.0.0        10.0.0.255      ether2-hot-lan
[paul@MikroTik] >

wlan1 and ether2 are using the same netmask which is what i assume you're talking about.

yet still. when i obtain an ip on my laptop i cant get a hotspot logon page.

I have the same issue, maybe you can help me..
ether1 (public to DMZ address): 10.0.0.2/24
wlan1 10.5.50.1/24 with hotspot.
I enabled srcnat with Outgoing interface ether1 and masquerading.

Some websites show,others not.
The DNS on the clients are in the following order:
1. 10.5.50.1
2. my public DNS
3. my public DNS
I have the DNS to allow remote lookups as well.

I don't know why some websites work, others don't and even the ones that work sometimes they don't work and so on.
Any suggestions?
Thanks much

SurferTim · Tue Jun 02, 2009 10:54 am

I would remove the 10.5.50.1 address from the dns settings. Just use your two public dns server ips there. If that doesn't help, you might want to start another post.

thomsany · Tue Jun 02, 2009 4:36 pm

I fixed the problem with the help of Mikrotik support.
The problem was that in my routes I had my Gateway set correctly but my Interface was pointing to my phisical connection.
After I removed the Gateway interface everything worked like a charm.

Hope this can help others with this problem.

Regards,
Teo
