hi, i am in the process of setting up an ISDN router for a network of three computers, using a 486 and running kernel 2.4.5 (because of the iptables functionalities). the system has one of the very old AVM A1 (Fritz!Classic) cards, which I can load and talk to with the hisax.o driver. it's at 0x200, but i don't know the IRQ, but I remember it being configurable through software, and the docs say that any free IRQ can be used.
i have used adrian bunk's packages for the 2.4.x kernels, and i have successfully configured everything for a dial-up to the German provider T-Online. I am experiencing a problem, which may be IRQ-caused, but it's weird and I don't think that IRQs are the cause. I can establish a connection with 'isdnctrl dial ippp0,' the system creates the PPP link, configures the routing table, and a second later, I can ping to the outside. it also looks as if UDP traffic works. However, whenever I initiate a TCP connection, the ISDN link goes down. the logs report the following: Jun 25 00:51:42 embryo ipppd[3516]: IPCP terminated by peer Jun 25 00:51:43 embryo ipppd[3516]: LCP terminated by peer Jun 25 00:51:45 embryo ipppd[3516]: Connection terminated.

Jun 25 00:51:45 embryo ipppd[3516]: closing fd 8 from unit 0 Jun 25 00:51:45 embryo ipppd[3516]: link 0 closed , linkunit: 0 Jun 25 00:51:45 embryo ipppd[3516]: reinit_unit: 0 Jun 25 00:51:45 embryo ipppd[3516]: Connect[0]: /dev/ippp0, fd: 8 Jun 25 00:51:45 embryo kernel: isdn_net: local hangup ippp0 Jun 25 00:51:45 embryo kernel: ippp0: Chargesum is 0 Jun 25 00:51:45 embryo kernel: ippp_ccp: freeing reset data ... this looks to me as if T-Online cuts the connection somehow, which is weird. I can dial up just fine to the same account with two other ISDN-enable computers... have you experienced something similar? i couldn't find anything on the AVM site, the HOWTO, isdn4linux, or a general google/linux search. any help or pointers appreciated. martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:"; [EMAIL PROTECTED] -- "finally, we have a president who knows how to run the government like a business. presuming the business is pets.com." -- gail collins
