As the dust settles I need some help
Ok, after 2 days of having a major headache with talktalk, i finally know where i stand with this however i would like to use the equipment i originally had and need some help... please bear with me.
Tuesday of this week everything was working fine and we could send and receive emails, provide external file access via HAP, use my cisco 1941 router, etc. Everything was a normal. Someone decided it would be a good idea to move our line rental for our broadband to talktalk. We were originally with Nildram (all those many moons ago) with a multilink (bonded ADSL) connection, who got taken over by opal, who then got taken over by tiscali. Anyway, after 10 years of things working correctly and smoothly and im going to hold my hand up, i didnt know how things were routed with the cisco 2600xm router as there was no paperwork or nothing was documented.
The time came to get a new router, i bought the cisco 1941 as it supported the dual adsl connection. I set it up by copying the config from the 2600xm and to my amazement things worked as they should.
A couple of years later (present time) we decide to change our line rental to talktalk... in hindsight.. a bad move but hopefully a better move in the future. This is where the fun starts.
I spoke to our account manager at talktalk who said that we could still have our multilink lines, keep our external IP ranges (a bank of 8 addresses) and still use our cisco 1941 router. I got my new username and password for my lines, however i found out that i had 2 username and passwords... which started the alarm bells ringing... why do i need 2 logins when i have a multilink line??? So i spoke to talktalk and they said that yep you just need to input the usernames and passwords into your box and away you go.... WELL... after a few phone calls later, i found out i had been given duff info from the start when really moving from a tiscali network to a talktalk network i cannot have a multilink line and i cannot keep my 8 IP addresses so the option now is to get ADSL fibre as my connection will be halfed, now down to 8meg. I spoke to my account manager at talktalk and said, pencil me in for the 18th April for fibre to be installed and i shall confirm that i want the fibre upgrade in the morning. I thought.. fine, yep, thats great. I went ahead and changed the username and password of the PPP chap details in the cisco 1941 router.
Things did not work from here and still dont continue to work 100%... where to start, this could get complecated.
The Cisco router would not route the internet connection to my smoothwall. The Cisco router was talking to the ISP without any problems as i could ping everything on the net via the router so i was obviously getting an IP from talktalk but since they had deleted/remove the bank of 8 IPs i initially had, of which the gigabitethernet0/1 port on the router had an address of 84.X.X.X 255.255.255.248 and the smoothie had an address of 84.X.X.X 255.255.255.248 which meant i could VPN into work. The exchange server / external email access was at 84.X.x.X 255.255.255.248 (configured on the smoothie) and external file access was at 84.X.X.X 255.255.255.248 (configured on the smoothie). I tried my best to try and get things to talk but now the pressure was on as i didnt have any internet access or email access.
The following day things clicked. I realised that talktalk had delete pretty much everything of my existing connection, so off to work i went with my home router to use at work. Plugged this in, set up the username and password and volah i have an internet connection that works but cannot receive emails or provide remote users with email or file access but can send emails. I thought since it was during the holidays things will be ok.. nope, how wrong was I? staff wanted to check their emails at which i said, sorry we are doing maintanence on our internet lines. I tried to get in contact with my account manager at talktalk who seems to have done a runner or is on holiday.
After trying to speak to my account manager i spoke to another account manager who made things a lot clearer and told me that what we had been given was false information.
Ive had to cancel my order for fibre so i can place an order for a bank of 4 IP addresses.
This is where i need your help.
I now have a bank of 4 public IP addresses with a /30 subnet (255.255.255.252). I have been told one of the IP addresses in the bank will be used to communicate between the router and the ISP. I plan to use one for the smoothie for a VPN connection, one for the exchange server and one for the external file access (HAP).
At the moment i have the crappy talktalk router talking to the smoothie... the crappy router local IP address is 192.168.X.X 255.255.255.0 and the smoothie on port 6 is configured 192.168.X.X 255.255.255.0.
Port 1 on the smoothwall is connected to the main switch and configured 172.X.X.X 255.255.248.0
How would i get my cisco 1941 router to be the main router here so i can get all my services working again? Well, at the moment, i would like the Cisco router to be able to provide an internet connection to the smoothie.
I have already emailed the domainadmin team and informed them of the IP to DNS change i need.
Would it help if i post an example of the config?
