I attempted to post the message below - only to have it not arrive at the local ISP server ....... UNTIL I had shut down Zone Alarm !!
I can understand, to some extent, why text - both Eudora and Newsgroup are similarly affected, but VoIP "phone" calls go thro' this Buffalo router okay.
Now read on......................[please].
.... And I thank you for the pointer; I had already printed out the WBR-G54 Manual to be found on the supplied CDROM, I've also printed the info from this site too. Actually I did go looking on Buffalotech for such info, I don't know how I missed it.
Since the original posting, I have discovered another anomaly with this Buffalo router. It is exactly the same problem I had with an earlier - highly expensive - wired Linksys -- Namely, with Zone Alarm active, it just will not allow not enormously large text files with or without attachments to get to my ISP's mail server to the world wide web. I have managed - occasionally - to get a 26.1 KB text file away. I sent it to myself as a "test". On other occasions, even small files of a few KB's - like 3~6KB just hang as Eudora version 3 *OR* 6 attempts to dispatch them. If I switch Zone Alarm [3.0.26] off, then there is a slight pause before the message leaves, but it DOES get sent to the mail server.
In my copy of Eudora 3, an "activity" bar shows the file being uploaded. With ZAlarm activated, the blue sliding indicator in this bar "sticks" at some point .... this sticking point depends on the file size. If the file is large, the indicator swiftly comes to a halt close to its starting point on the left. If the file is small, then it may make it almost to the end of its travel. If the file is just a few words - then the blue slider will quickly whizz across to the right, and the message is sent out okay.
Now, this occurred with my original Linksys, and the maker disclaimed any knowledge of why I was seeing what I again am seeing; and for the life of me, I can't recall for sure what, if anything I did to cure this problem !
I'm just wondering if I "adjusted" the packet size somewhere in the Linksys setup, and whether I should try it again with the Buffalo ?
I've got 3 routers here, one wired one out of China which works well & e'mails just whizz thro' it with Zone Alarm protecting me. An "Agilan" 'b' type wireless router which similarly is set to make port 113 invisible & which handles Eudora e'mails with no problems at all, and finally, my "upgrade" 'b' & 'g' Buffalo router into who's "Buffalo Chips" I have stumbled. . I know that I *ought* to be able to effect a "fix" - but so far, whenever I need to send e'mails, I ABSOLUTELY HAVE TO shut down Zone Alarm just to get the e'mails away --- & then remember to re-enable ZA afterwards.
So, I will read the Buffalo "User Manual" and see if it has any "pointers" there. Certainly the Buffalotech website offers no solutions in their techsupport sections.... that's why I'm struggling now. .
Anyone got further ideas? I could sure use some !
