When I first got DSL service I found it necessary (for reasons I'm not sure I remember clearly)
to route it through a wired router (LinkSys Cable/DSL Router) to my computer. Seeing no need
for it now, I removed the router and connected the modem directly. But now when I want to
send e-mail via YAM, I get "Connected, awaiting welcome message" for 75 to 90 seconds
before the mail goes. If I replace the router, posts go immediately again.

Stranger and worse yet, if I want to reply to a post in Sylpheed (AmiCygnix), once I hit "Reply"
it takes over two minutes for the edit window to appear and everything else (typing, etc.) slows
down drastically as well.

I don't suppose the router uses that much electricity, but I'd rather do without it, and I don't
understand why having or not having an intervening router should have this kind of effect.

Does this make sense to anyone?

@kilaueabart
It's possible your modem was handing the public IP address to your router, and now its handing it directly to your computer. The bad thing about that is you've lost security that the router provides because anyone on the Internet can make connections directly to your computer.

About the odd software behavior, it's possible your computer is having to do some DNS lookups that it did not have to do before. I don't suggest you keep using your connection without the router, but if you do, you might try adding some local DNS entries for your computer's public IP, and also the mail server you connect to. It may be futile though since those addresses probably change periodically.

I appreciate your response. It reminds me of some settings I had to make in my router having to do with IP's. I had hoped to find something similar in the modem, but I guess it's just not there.

Until I can get my SAM working with wi-fi (that should be secure) I will after all replace the router.

@kilaueabart

Well a router will also give you a firewall so you probably should leave it set up. Direct from your router gives you no hw firewall at all. And if you are using Aos4 you would have no fw at all software or hw.

I use this for my Peg2 and it works flawlessly. I use DD-WRT.

It sounds as if your machine tries to look for a DNS that isn't responding, then it gives up and the backup DNS responds immediately. Has happened to me on several occasions in several OSes.

Can you find out what DNSes it is using? Not using an Amiga here, so don't know what command would show this for you

@TheKorn

I use a Raspberry Pi (which is also performing other tasks) in order to do the same thing.

I have a wireless card in my SAM but routing via the Pi with an 802.11n dongle is noticeably faster than the internal 802.11a/b PCI card.

It's sweet, you can put your Miggy anywhere in the house, you don't need a wireless network card (or drivers) and you get the latest protection.

@TheKorn

or he can use something like HomeNet... 1 cable and 2 sockets via power cables.
and inside them there's the NAT among other things.

So far I've been able to google "HomeNet" and get one computer store with helpful employees, one HomeNet that is downloadable software (with free trial -- I bet it doesn't do anything on an Amiga), and Home Networking Architecture for IPv6.
I'm not sure what IPv6 actually is, or the IPv4 that it seems I currently have, but I found a test that scores me "0/10 for your IPv6 stability and readiness, when publishers are forced to go IPv6 only."

OK, regoogling with "HomeNet socket cable" got me something more likely to be what you mean, including a 44-page catalog from www.UKHomeNet.co.uk, but I have the idea the sockets are wall sockets, which I probably wouldn't be allowed to install.

He means powerline adapters like these.

I thought maybe I could find the DNS my wired router uses for internet connection, but it gives blanks for both Host Name and Domain Name.

I was going to check the DSL modem, but apparently I can't get it in a browser if the wired router is in the way! I don't think it had anything of interest when I looked before replacing the router.

@Rose
I already have two of those. But I'll still have to use the wired router for firewall purposes.
(And, of course, to e-mail from YAM without waiting forever.)

It sounds like you have some configuration issue on the Amiga side.

It's possible that the DHCP server on the modem works differently than the one on the router, maybe giving you the DNS servers in reverse order instead of using the router itself as a DNS server, and unless you requested a fixed IP with your DSL service you might have no choice but to use DHCP instead of manual configuration.

You could let it use DHCP to configure the correct IP the first time and then make a note of the IP, gateway, DNS servers settings (use C:ShowNetStatus) and switch to manual to reconfigure it with different DNS settings.

Additionally the modem may use a different MTU, and other network-related settings which have an impact on performance, but you can adjust those manually in RoadShow via the GUI, editing text files, and using variables in ENVARC:Roadshow/TCP. It's not easy to configure but it's possible.

As for IPv6, there is currently no support for it on the Amiga, it's not that big of a deal as modern routers can act as a gateway between IPv4 on the LAN side and IPv6 on the WAN side. It could become an issue eventually, should servers start to use IPv6 exclusively, but I don't foresee it happening anytime soon.

As for firewalls, you don't need any with OS4 as it simply can't answer incoming requests if there is no server running on a given port, but if you are concerned about rogue applications running servers and sending data out behind your back, you can use IPF (IP Filter which comes with RoadShow) and create rules to limit what type of traffic, what ports and IPs are allowed in/out.
(see SYS:Documentation/RoadShow/IP-Filter)
