RE: [pfSense Support] Problem accessing some sites

[Holger Bauer]

Very strange and I have no clue atm. I firtst thought of ISP issues but as it 
is working with the netgear...hm, anybody else has a thought?

Did you check if the settings of the WAN interface are the same assigned by 
your provider at the netgear and the pfsense when you are connected? Also test 
with the netgear what the mtu of the link is. You can do that by ping 
provider gateway IP -l mtu-28 overhead -f. Maybe you have a very low mtu 
for that link. As ebay.de is blocking ICMP it might be a problem with path-mtu 
discovery and setting it to low mtu by default might help.

Other than this I'm out of ideas for now.

 Hi Rainer,

 Well, the site resolves, but it seems it can not connect - or only 
 garbage comes through.
 
  Does the IP resolve?
 
 
 Yeah, sure.
 It does.

 I can access www.spiegel.de, heise-newsticker - and it's way 
 faster than 
 with the old Netgear.
 
 With ebay, Firefox just says Waiting for www.ebay.de until 
 it times out.
 I can also access www.t-online.de.
 
 
  What kind of WAN do you have? Sounds like PPPoE? Please add 
 some details.
   
 
 
 
 OK, yes, it's PPPoE - I'm sorry for omitting this.
 
 It's a company sponsored DSL-line in Switzerland (1200/200) 
 with fixed 
 IP, provided by Internet Pipeline AG.
 
 
 
 
 cheers,
 Rainer

Hi Rainer,

I have no issues accessing ebay.de from behind different pfsenses. What is the 
problem you are seeing exactly? Does the IP resolve? What kind of WAN do you 
have? Sounds like PPPoE? Please add some details.

 Hi,
 
 it seems I can't get to sites like www.ebay.de.
 I'm using the embedded image for WRAP. It's dated Feb 9th.
 I've set the MTU to 1460 and 1452 bytes (and 1400), but this seems to 
 cause a lot more problems than it solves.
 
 The stinky 4 year old Netgear MR314 can do it with no problems and no 
 messing-around with MTU-values - but it's much slower than 
 pfsense (at 
 least without reducing the MTU...).
 
 
 What should I do?
 
 
 cheers,
 Rainer
